Re: Admin Role - protected admin folder

mehryad — Wed, 02 Dec 2009 05:00:00 GMT

I think what you should do is write a couple of lines of code to handle the Page_Load() event in the login.aspx. The code below checks to see if admin redirects to Admin Home; if Member redirects to Default (or wherever you want it to go) and if neither (anonymous) does nothing and therefore loads the Login.aspx page

if (User.IsInRole("admin"))

{

Response.Redirect("~/");

}

if (User.IsInRole("member"))

{

Response.Redirect("~/");

}

if (User.IsInRole("admin"))

{

Response.Redirect("~/AdminHome.aspx");

}

if (User.IsInRole("member"))

{

Response.Redirect("~/Default.aspx");

}

Hope this helps! Don't forget to mark as answer if it does

Re: Http Response Content Length

Robotuner — Sat, 14 Nov 2009 05:00:00 GMT

Apparently, what I intended to do doesn't work and I don't have any idea what is wrong. As described above, I need to send a response back, so this the complete response that I intended:

protected void Page_Load(object sender, EventArgs e)
    {
        //now post back the key.
        String hashValue="someTypeOfKey";
        Response.ContentType = "application/www-url-encoded";
        Response.AddHeader("Key", hashValue);
        Response.Write(sb.ToString());
        Response.End();

}

What is getting returned is:

HTTP/1.1 200 OK
Content-Type: text/html; charset=utf-8;
Content-Length: -1

It does not appear that the Response values have been changed.

What am I omitting or doing wrong?

HELP: How to force an aspx page to always be served vs. using cache...

celoftis — Wed, 01 Jul 2009 04:00:00 GMT

Using VS2005, VB code behind and javascript.

I have several pages that when accessed for a second or subsequent times always need to hit the server - but what I'm seeing with some users is that they are accessing cached pages. I want to force these pages to always get the latest page from the server.

From client side javascript I know how to set the "if-modifed-since" request header to ensure that my xmlHttpRequest's are always served, i.e. "xmlHttp.setRequestHeader("If-Modified-Since", "Sat, 1 Jan 2000 00:00:00 GMT");". When I view the request headers collection from this request I see "If-Modified-Since" with a value of "Sat, 1 Jan 2000 00:00:00 GMT" in the list.

My problem is that I want my aspx page requests - not just ones that originate from javascript - to have the "If-Modified-Since" request header set to an old date. Stated another way, I want all my pages to come back with the "If-Modified-Since" value in the Header's collection set to some date (i.e. "Sat, 1 Jan 2000 00:00:00 GMT") that will ensure that the page gets served from the server vs. cache.

Having javascript requests under control, I now need to do the same for all my aspx pages. Here is what I have tried in my code behind.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

Response.AddHeader("Last-Modified", "Sat, 1 Jan 2000 00:00:00 GMT")

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

Response.AddHeader("Last-Modified", "Sat, 1 Jan 2000 00:00:00 GMT")

Response.AddHeader("If-Modified-Since", "Sat, 1 Jan 2000 00:00:00 GMT")

End Sub

Neither of the options above produce the "If-Modified-Since" value in the request's header.

Anyone have an idea what I am doing wrong?

Open file in a new tab (via WriteFile)

Hanfwurst — Wed, 29 Apr 2009 04:00:00 GMT

Hello everyone.

Here is my problem: I'm opening a .pdf file in the browser via Response.WriteFile. It works perfectly fine! But now I'd like to open that file in a new tab (a new window would work too, but I'd rather have it in a new tab). How can this be achieved? Here is my code snippet:

1            protected void SpezE_Click(object sender, EventArgs e)
2            {
3    
4                string finalerPfad = Pfad + myFileName;
5                string fileLength;
6                FileInfo myFileInfo = new FileInfo(finalerPfad);
7                fileLength = myFileInfo.Length.ToString();
8    
9                Response.Clear();
10   
11               Response.AddHeader("Accept-Ranges", "ascii");
12               Response.AddHeader("Content-Length", fileLength);
13               Response.AddHeader("Cache-Control", "post-check=0, pre-check=0");
14               Response.ContentType = "application/pdf";
15               Response.AddHeader("Content-Disposition", "inline; filename=\"" + myFileName2 + "\"");
16               Response.AddHeader("Cache-Control", "no-store, no-cache, must-revalidate");
17               Response.AddHeader("Pragma", "no-cache");
18   
19               Response.Flush();
20               Response.WriteFile(finalerPfad);
21               Response.End();
22           }

EDIT: I don't know now, if I accidentally posted this Tread into the "Get Started" section or if it "got moved" here. Sorry if it's in the wrong section.

Kind Regards

PNG Image to stream to HTTP Response problem

fraserhardy — Wed, 25 Mar 2009 04:00:00 GMT

Hi,

I have an asp.net 3.5 page which depending on a string passed to it, retrieves an image from a URL. I then need to pass this image back via a HTTP Response.

the code I have is:

 Dim wr As WebRequest = WebRequest.Create(URL)
        Dim wre As WebResponse = wr.GetResponse

        Dim ms As Stream = wre.GetResponseStream

        Dim streamreader As StreamReader = New StreamReader(ms)
        Response.ContentType = "image/png"
        Response.AddHeader("Content-Length", wre.ContentLength.ToString)
        Response.Write(streamreader.ReadToEnd)

Problem I am having is that I get an image not vaild message in my browser.

Any advice would be greatly apreciated.

Regards,

Fraser

HttpContext.Current.ApplicationInstance.CompleteRequest() vs Response.End()

tomliversidge — Fri, 13 Feb 2009 05:00:00 GMT

Hi,

I am confused as to the best way of ending requests. Two functions in my web application send content to the browser - PDF generation from database content and sending files on the server to the browser. I have read about the various options but am still not sure about which is best to use. The Response.End generates a ThreadAbortException. What impact does this have on an application? (it is not being called within a Try Catch block). Using HttpContext.Current.ApplicationInstance.CompleteRequest() doesn't throw the exception, but still executes the rest of the page events, which could cause problems.

see http://www.c6software.com/CodeSolutions/dotnet/ThreadAbortException.aspx
also http://www.sagara.net/post/2008/04/05/ResponseRedirect-and-the-ThreadAbortException-and-why-ite28099s-a-good-thing.aspx

I guess my question is, is it safe to have ThreadAbortExceptions thrown in my application? What impact is this likely to have?

Thanks

Response.End causing user to sign out of website?

silverCORE — Mon, 19 Jan 2009 05:00:00 GMT

Hi, I have an asp.net 2.0 website hosted at DiscountASp and I have this webpage that does the typical Response.WriteFile and Response.End to present the user with the download file dialog box.

but sometimes it seems to be causing the user to be signed out of the application...with the whole "ReturnUrl" parameter on the query string.

has anyone had this problem, or is there a way around it?

I also tried changing response.End for HttpContext...CompleteRequest, but no luck, it keeps hapenning.

any help or ideas are greatly appreciated, thanks.
