URL rewrite (RewritePath) in Global.asax BeginRequest...

Pettt[cz] — Tue, 01 Dec 2009 05:00:00 GMT

http://pet3.aspone.cz/

Trivial URL rewrite (RewritePath) works perfect on my development PC. Can't get it to work on provider IIS.It ends up on 404 page, no matter what I try.
Tried:
runAllManagedModulesForAllRequests="true" in webConfig
both, Classic and Integrated AppPool setting

Development:
VS2008 with integrated web server (Cassini)
Production:
IIS7

Global.asax Code:

Private Sub Global_asax_BeginRequest(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.BeginRequest
        Dim app As System.Web.HttpApplication = DirectCast(sender, System.Web.HttpApplication)
        Dim requestedUrl As String = app.Request.Path.ToLower()
        Select Case requestedUrl
            Case "/url/link-01"
                app.Context.RewritePath("~/URL01.aspx", False)
            Case "/url/link-02"
                app.Context.RewritePath("~/Default.aspx?Id=222", False)
        End Select
        ' rewrite URL
End Sub



thanx all

Error Handling Problem

gucc — Tue, 01 Dec 2009 05:00:00 GMT

Im trying to create some error handling for my website, but i'm having some problems. i put together some code to catch the method, line number etc, but it doesn't help me much when the error happens in my data access layer, because i use that 100s of places. is it somehow possible to catch the page that triggered the method who generated the error?

my code produces something like this:

Invalid column name 'CurrentAction_Unit'.

Produced Error At 30/11/2009 18:20:29

Invalid column name 'CurrentAction_Unit'.
File Name: D:\Projects\customTools\customTools\System.Data\DataAccessLayer\DataAccessLayer.cs
Method Name: System.Data.DataTable ExecuteDatatable(System.String, Boolean)
Error Line Number: 154
Error Column Number: 17

User Generated This Error: razer at TownID 216

and its really not any helpful to me. i either need the parameters sent, or what page or class triggered it, so i can track it down.

this is my current code:

void Application_Error(object sender, EventArgs e)
    {
        // Code that runs when an unhandled error occurs
        DAL d = new DAL("ArmaTribes_Data");

        Exception ex = Server.GetLastError().GetBaseException();
        StackTrace st = new StackTrace(ex, true);

        string errorMessage = "";
        foreach (StackFrame sf in st.GetFrames())
        {
            if (sf.GetFileLineNumber() > 0)
            {
                errorMessage += "<b>" + ex.Message + "</b><br /><b>File Name:</b> " + sf.GetFileName() + "<br /><b>Method Name:</b> " + sf.GetMethod() + "<br /><b>Error Line Number:</b> " + sf.GetFileLineNumber() + "<br /><b>Error Column Number:</b> " + sf.GetFileColumnNumber() + "<br /><br />";
            }
        }

        errorMessage += "<br /><span style='color: red;'>User Generated This Error: " + HttpContext.Current.User.Identity.Name + " at TownID " + Session["TownId"] + "</span>";

        string errorType = EventLogEntryType.Error.ToString();

        d.Addparameter("@ErrorTitle", ex.Message, SqlDbType.NVarChar);
        d.Addparameter("@ErrorText", errorMessage, SqlDbType.Text);
        d.Addparameter("@ErrorType", errorType, SqlDbType.Text);
        d.ExecuteNonQuery("INSERT INTO Log_Error (ErrorTitle, ErrorText, ErrorType) VALUES (@ErrorTitle, @ErrorText, @ErrorType)");
    }

any help is greatly appriciated

Global.asax Application_BeginRequest fired after load events

kipusoep — Tue, 01 Dec 2009 05:00:00 GMT

Hi!

Building another website with umbraco, which features multilanguage.
So I have a cookie and want to set the current thread's CurrentCulture with the selected culture inside this cookie.

I'm using the following code:

public class Global : umbraco.Global
{
        protected void Application_BeginRequest(object sender, EventArgs e)
        {
                HttpCookie objCookie = Request.Cookies["culture"];
                if (objCookie != null && !string.IsNullOrEmpty(objCookie.Value))
                {
                        try
                        {
                                CultureInfo objCulture = new CultureInfo(objCookie.Value);
                                System.Threading.Thread.CurrentThread.CurrentCulture = System.Threading.Thread.CurrentThread.CurrentUICulture = objCulture;
                        }
                        catch { }
                }
        }
}

Inheriting from System.Web.HttpApplication doesn't change anything for me.

The problem is; when I put a breakpoint on the first line of code and on the OnInit/OnLoad/OnPrerender in some masterpage's codebehind, the loading breakpoint get's hit first, instead of the Application_BeginRequest begin called first... :-/

This is really odd behavior. It does work however, when using the ASP.NET development webserver (instead of IIS 7.5 (win 7) or IIS 7 (win server 2k8)). It does also work like expected, when switching the Pipeline mode to Classic, but that will break the UrlRewriteNet plug-in.

Does anyone know what's going on?

Re: Cannot view the .aspx page ! (Runtime Error)

I'm not entirely sure what you can and cannot gain access to on your server. Can you create a 'Logs' folder in your web root? If so, create one and then create a Global.asax file in your web project. Replace the Application_Error handler in Global.asax with this code. It's just a snappy bit of code to create a log file containing the exception causing your site to crash:

void Application_Error(object sender, EventArgs e) {
        Exception ex = Server.GetLastError().GetBaseException();        
        StringBuilder sb = new StringBuilder();
        sb.Append(DateTime.Now.Year.ToString());
        sb.Append(DateTime.Now.Month.ToString());
        sb.Append(DateTime.Now.Day.ToString());
        sb.Append("_");
        sb.Append(DateTime.Now.Hour.ToString());
        sb.Append(DateTime.Now.Minute.ToString());
        sb.Append(DateTime.Now.Second.ToString());
        sb.Append(DateTime.Now.Millisecond.ToString());
        string dt = sb.ToString();        
        using (System.IO.StreamWriter sw = new System.IO.StreamWriter(
            Server.MapPath(VirtualPathUtility.ToAbsolute("~/Logs/")) + dt, true)) {
            sw.WriteLine("Logged: " + dt);
            sw.WriteLine("Request: " + Request.Url.OriginalString);
            sw.WriteLine("Form: " + Request.Form.ToString());
            sw.WriteLine("Exception Message: " + ex.Message);
            sw.WriteLine("Target Site: " + ex.TargetSite);
            sw.Write("Stack Trace: " + ex.StackTrace.Trim());
            sw.Flush();
        }
    }

Events of Global.asax not fired on webserver "Application_Error"

suyash123 — Sat, 21 Nov 2009 05:00:00 GMT

Hello guys,

i was performing url rewriting on my asp.net application.

i google and found a technique that in Application_Error event handeler of global.asax we can find the wrong Url and redirect to a correct page by server.transfer and sending some query string with it.

I done the same thing. i used Application_Error event of Global.asax and checked if error occurs then redirect it to a known .aspx file with querystring as some part of url

But i m facing a problem in it.

This code totally works on local server on my PC. but when i put it on my webserver. it just absultely failed.

I fouund that the events of global.asax are not even getting fired.

So what should i do .

Check my code in Application_Error

void Application_Error(object sender, EventArgs e)
    {
        // Code that runs when an unhandled error occurs

        string str = Request.Url.AbsoluteUri.ToString();   // to check who had made a request Png/css/aspx/htm....

        string mypath = Request.ServerVariables["PATH_INFO"]; // to get the request path

        if (mypath.Contains(".aspx") || mypath.Contains(".css") || mypath.Contains(".png"))
        {
            //If requested url contains .aspx in it then no need of url rewriting
        }
        else
        {
            string strUrlNavigate;
            string strQueryString;

                char[] CharKey = { '/' };                  //Character used by split methord to split the string
                string[] strKeyWords;                      //Array holding the spliteed Url
                strKeyWords = mypath.Split(CharKey);       //Split the url with seperator as "/"

                strUrlNavigate = strKeyWords[strKeyWords.Length - 3].ToString().Trim(); //it holds to what page we have to redirect i.e. Market-reports(Report.aspx),market-research(category.aspx)

                strQueryString = strKeyWords[strKeyWords.Length - 2].ToString().Trim();   //it holds the value of Query string

                strUrlNavigate = strUrlNavigate.Replace(".aspx", "");     //Remove the.aspx if present .. no use

                if (strUrlNavigate == "market-research")
                {
                    //navigate to Category page

                    string strPath = Request.ApplicationPath.ToString().Trim(); // to Get the application path (Local: /httpdocs , website: http://www.biotechmar.com)

                    string destinationHost = Request.ServerVariables["HTTP_HOST"]; // to check it is Loacl host request or server request


                   Request.ApplicationPath.ToString() + "/Category.aspx?q=" + strQueryString; // redirect path mapping

                    Response.Status = "200 OK";        // Page request is Successfully redirect and page is found

Server.Transfer("Default.aspx?q=" + destinationUrl); // With this the Url in browser is same only the Page is redirected

//Server.Transfer(destinationUrl); // With this the Url in browser is same only the Page is redirected

                }
                else
                {
                    if (strUrlNavigate == "market-reports")
                    {
                        string strPath = Request.ApplicationPath.ToString().Trim(); // to Get the application path (Local: /httpdocs , website: http://www.biotech.com)

                        string destinationHost = Request.ServerVariables["HTTP_HOST"]; // to check it is Loacl host request or server request

                        string destinationUrl = Request.ApplicationPath.ToString() + "/Report.aspx?q=" + strQueryString; // redirect path mapping

                        Response.Status = "200 OK"; // Page request is Successfully redirect and page is found

                        Server.Transfer(destinationUrl); // With this the Url in browser is same only the Page is redirected

                        //Response.Redirect();

                        // Context.RewritePath(destinationUrl);

                        // Context.Server.Transfer(destinationUrl);
                    }

                }

MVC URL issue

nkpatro — Mon, 16 Nov 2009 05:00:00 GMT

Hi,

I'm new to MVC. I was trying figure out if there is a way to change/rewrite the URL.

For Example : I have the folllowing urls

http://www.example.com/Home/Index

http://www.example.com/Home/About

How do I rewrite the above urls to read as below

http://www.example.com/Index

http://www.example.com/About

but they should still be under HomeController.

Please advise.

thanks

Error with Server.Transfer() in Application_BeginRequest/Application_Error() in global.asax

suyash123 — Wed, 11 Nov 2009 05:00:00 GMT

Hey guys,

Recently i was woking on URLRewrition on my website. i did a lot of googling to get concept of url in asp.net which suite my application.

I found one but i m faing a problem in please help!

The 1st Page of my web page opens normally. in that page there are lots of link which are UrL rerewriten . on click on those page ther will be 404 errar as page not found.

I temporily handle this by navigate that request to a rewrite.aspx byconfiguring 404 error page custumisation in IIS/Control panel of my website.

in that page i break the url and detect to which page i want to navigate and navigate to that page by server.Transfer.

But this is very raw technique and is least efficent.

I found a technique on site that we can do urlrewriteing with help of Application_BeginRequest() in Global.asax.

Page request is

www.abcdef.com/market-reports/pharmareport/

it should navigate to

Report.aspx?q=pharmareport

My Code is

string mypath = Request.ServerVariables["PATH_INFO"];
        string filename;
        string strUrlNavigate;
        string strQueryString;

        filename = mypath.Substring(mypath.LastIndexOf("/"));
        filename = filename.Trim();
        filename = filename.Replace("/", "");

        if (filename == "")
        {

            char[] CharKey = { '/' };
            string[] strKeyWords;
            strKeyWords = mypath.Split(CharKey);

            strUrlNavigate = strKeyWords[strKeyWords.Length - 3].ToString().Trim();
            strQueryString = strKeyWords[strKeyWords.Length - 2].ToString().Trim();

            // strUrlNavigate = strUrlNavigate.Replace("/", "");
            strUrlNavigate = strUrlNavigate.Replace(".aspx", "");

                if (strUrlNavigate == "market-reports")
                {
                    string strPath = Request.ApplicationPath.ToString().Trim();

                          // string destinationHost = Request.ServerVariables["HTTP_HOST"];

                    string destinationUrl = Request.ApplicationPath.ToString() + "/Report.aspx?q=" + strQueryString;

                    Response.Status = "200 OK";
                   Server.Transfer(destinationUrl);

                    // Response.Redirect(destinationUrl);

                    // Context.RewritePath(destinationUrl);

                   // Context.Server.Transfer(destinationUrl);
                }

            }

By this i wil find to which page i want to navigate and what shuld be passed as query string.

But i Want to keep url in browser as it is so i have to Use Server.Transfer() mandatorily.

but it throws a exception as.

Eroor:

"Error executing child request for /httpdocs/Report.aspx."

The 'href' property had a malformed URL: Cannot use a leading .. to exit above the top directory..

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Web.HttpException: The 'href' property had a malformed URL: Cannot use a leading .. to exit above the top directory..

The 'href' property had a malformed URL: Cannot use a leading .. to exit above the top directory..

also i tried the above code in

Application_Error() { }

But it gave a same problem.

I found a solution that recomends me to use responce.redirect . But it chage the URL and i don't want to change it.

What is problem with server.transfer and what should i do?

In order for the Global.aspx.vb file to recognize your DataAccess class it needs to know what DLL is came from. Specifically, it needs to know the namespace name.

Add this to the top of the file.

Import <NameofDataAccessNamespace>

Also, Global.asax.vb belongs in the root of a WAP project. I am not sure why you had it in the app_code folder in your web site project because that is not the correct place. Global.asax & Global.asax.vb always belong in the root node.

Hope this helps

Re: url rewriting

iGulfam — Tue, 20 Oct 2009 04:00:00 GMT

Not very tough.

You can do this is Global.asax, and you will have to use the "application_beginrequest" event. Following is a sample code

Dim initialurl As String = ""
            initialurl = Request.Url.ToString
            If initialurl.ToLower.IndexOf("users_") >= 0 Then
                Dim mTemp As String = initialurl.Substring(initialurl.LastIndexOf("_") + 1)
                mTemp = mTemp.Substring(0, mTemp.LastIndexOf(".aspx"))
                Dim mUserID As Integer = GetUserIDByName(mTemp) 'Your funtion to get UserID using User name.
                If mUserID <> 0 Then 'Suppose your funtion return 0 in case no User s registered for the name you checked.
                    Dim stargeturl As String = "userprofile.aspx?uid=" & mUserID
                    Context.RewritePath(stargeturl)
                Else
                    Response.Redirect("http://www.YOURWEBSITE.com")
                End If
            Else
                Response.Redirect("http://www.YOURWEBSITE.com")
            End If
