  Url Rewriting; 404 not found on deployment server

  Apr 20, 2010 09:20 AM|LINK

  It supposed to be that using httpModules could rewrite Urls to be handled by ASP.net engine, and then write .ashx handlers to return intended files; all of this without any physical access to the server. For my website I have written httpModules and [.ashx] httpHandlers for .apsx. .xml, .xap, and image files. All handlers work pretty much the same way: "category" directory is imaginary; remove that from uri and return the file. For example: ~/category/default.aspx returns file at ~/default.aspx

  This website works perfectly in my testing environment. However, on the deployment server (godaddy, shared) if I use Url Rewriting (my request starts with /category) only if I requested .aspx page it gets returned; all other types return 404 not found!

  http://www.shopstaple.net/category/dzDebug.aspx

  returns default.aspx (good)

  http://www.shopstaple.net/category/ClientBin/GeneratedImages/dzDebug/Metadata.xml

  returns 404

  http://www.shopstaple.net/category/ClientBin/GeneratedImages/dzDebug/dzc_output_images/sunset_files/9/0_0.jpg

  returns 404

  I looked in the web.config and saw <system.webserver> did not duplicate everything in <system.web>, so I added the handler

  Why .aspx pages reroute fine, but the types handled by a .ashx each (.xap, .xml, .jpg), return 404?

  <add name="zzzzashxHandler" verb="*" path="*.ashx" type="System.Web.UI.SimpleHandlerFactory"/> to it. I published that to the deployment server, and still no luck. Can anyone tell me how to find out what is wrong?

  Deployment server: shared server, godaddy, [most likely medium trust, ] ASP.net 3.5, IIS7

  　

  Here is a simplified version of my web.config. I might have errors in <system.webserver>:

  Here is also my xmlHandler.ashx:

  using System;
  using System.Web;
  
  namespace XMLHandler

          {
              get { return false; }
          }
  
          public void ProcessRequest(HttpContext context)
          {
              context.Response.Clear();
              context.Response.ContentType = "text/xml";
              context.Response.ContentEncoding = System.Text.Encoding.UTF8;
  
              string[] UriSections = context.Request.RawUrl.Split(new Char[] { '/' });
              if (!(UriSections[2] == "category" && UriSections[3] == "ClientBin" && UriSections[4] == "GeneratedImages"))
                  throw new Exception("Requested xml file outside of category/ClientBin/GeneratedImages directory.");
              System.Text.StringBuilder xmlFile = new System.Text.StringBuilder("");
              for(int i=0; i<UriSections.Length; i++)
              {
                  if (UriSections[i] != "category")
                  {
                      if (i == UriSections.Length - 1)
                          xmlFile.Append(UriSections[i]);
                      else
                          xmlFile.Append(UriSections[i] + "/");
                  }        
              } 
              context.Response.TransmitFile(xmlFile.ToString());
          } 
  
      }
  }
