Our website used to be a php website, now everything changed to .net, but the customer still want to keep the original php Request url. I want to know How to set Handler mapping on IIS7 to redirect .php file to .aspx file ? In more details, when you click handler mappings on IIS 7.0, what kind of hanlder should you add (add managed handler or add script map or add wild card script map or add module mapping) to redirect .php file to .aspx file?

View 2 RepliesI am having a specific requirement of which I am not sure it is even possible to do but I have read somewhere in the past few days that similar to what I am trying to achieve shoud be done by writing a custom HttpHandler (or module?). Basically, I currently have a simple aspx page that accepts a file upload and forwards it to another URL (after doing some checking). The way this currently works is that my Page_Loaded gets called only after the entire file is uploaded.
What I am looking to achieve is get a hold of an uploaded file Stream early on as soon as request headers are processed so I could do some sort of piping froim the uploaded file Stream to my destination Stream. With large files this should be extra beneficial because there is no waiting time for the large file to get uploaded and my gut feeling tells me this way the memory footprint should also be lower. What I need is a forward-only Stream. No seeking needed. Therefore, I don't need to manage the entire uploaded file at some point in time. I just want to send the bytes as soon as they are received (with some lightweight processing in between).
I have the below code which does not work. I cannot instantiate my class this way.
SecurePage secureCs = new SecurePage();
I want to be able to inherit the class instead of instantiating.

View 2 RepliesI have implemented URL rewritting in my application. I did it in Application_BeginRequest located in Global.asax. My url rewritting in working fine. Now in order to maintain rewritting during post back.
I have added code line this.Form.Action = Request.RawUrl; in page load event in order to maintain rewritten URL during post back. When I am adding below code on image button click to download file it doesn't work. It says "Internet explorer cannot display webpage". When I am removing line this.Form.Action = Request.RawUrl; from page load then downloading file will start working but URL rewritting will not work on postback.
FileInfo objFi = new FileInfo(Server.MapPath(filepath));
this.Form.Action = Request.RawUrl;
HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment; filename=" + objFi.Name);
HttpContext.Current.Response.Charset = "";
HttpContext.Current.Response.AddHeader("Content-Length", objFi.Length.ToString());
HttpContext.Current.Response.ContentType = "application/octet-stream";
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.WriteFile(objFi.FullName);
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.End();

I have an httpmodule and it has a handler for OnEndRequest. I am trying to write the HttpContext.Response.OutputStream to a file. I am trying to use the Read method of it. But when it is called the exception message i get is "Specified method is not supported". So i am not able to do what i want that is, write the response to a file on the disk. I am able to write the HttpContext.Request.InputStream to a file using its Read method which i do in a handler for OnBeginRequest.
View 2 Repliesi manage the doc extension through a customized HttpHandler :
I set <add verb="GET" path="*/*.doc" type="MOMA.IWT.Framework.Portal.Components.HttpHandler.ResourcesHandler, PortalComponents" /> in the httpHandlers section of the web.config file and in IIS property i add a mapping for .doc with C:WINDOWSMicrosoft.NETFrameworkv2.0.50727aspnet_isapi.dll

View 3 RepliesI have read in many places that referencing IRequiresSessionState or IReadOnlySessionState will allow me access to the Session scoped variables from within the ProcessRequest method in an ASHX file.
I have implemented these changes, as follows, and I am unable to retrieve this data still, as the server returns a null object reference error:
using System;
using System.Web;
using System.Web.SessionState;[code]....
The error is most certainly specific to pulling data from the session, yet I am 100% certain that the session contains data in this key.
It shouldnt matter where I am storing the data (cookies, vs db, etc), right?
This seems as good a place as any for this question. It has to do with an .ASHX handler.
I have written a generic file serving handler in asp.net/vb.net - it has been working great. I recently moved to a windows 7 box and am now debugging under IIS7, and this is where the problems occure.
Whenever I serve a file to either FireFox or Chrome (IE8 works fine) from IIS 7, the download will fail.
- In FireFox the error is "[some file name and path].part could not be saved, because the source file could not be read."
- In Chrome the error is "Error 330 (net::ERR_CONTENT_DECODING_FAILED): Unknown error."
- In IE8 it works fine
If I run the same code in IIS6, it works fine. If I run the same code in the Visual Studio virtual web server, it works fine (on windows 7 or XP).
I am rather concerned about this as our production web server will soon be IIS7; which I'm starting to really love, and would hate to revert to IIS6 just because this won't work in IIS7.
Here is the code I'm using..I've tried a number of different patterns. It seems to always fail on the Flush() line with the error "System.Web.HttpException = {"The remote host closed the connection. The error code is 0x80070040."}"
One thing I have noticed, if I move the flush statment to the finally clause or remove it all together; firefox will attempt to read the entire file - it appears to be looping through the entire block of code just fine, until it hits the flush statement. If I remove the flush statment I still get an error and it still tries to read the entire file before asking me to save it.
--Edit: I removed the flush and tested again; firfox thinks it downloaded a zero byte file.
I'm assuming I just have some sort of header issue going on here, but I'm at a loss at this point as to what that would be.
