HttpHandlers / Modules :: Set Handler Mapping To Redirect .php File To .aspx File On IIS7?
Mar 15, 2011
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?

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.

i have a custom handler which captures user's book mark entry. To debug this handler, i have created a file "test1.txt" in code behind which saves the user entry. After the debug, i removed the text file (test1.txt) then re-complied the web app and deployed new DLLs for the site. But, the site is still looking for test1.txt file. i dont know how to confirm if the handler is really removed from the new DLL. Also, looked at the handler code behind file and didn't find any entry with test1.txt. So,

I have an Handler.ashx file and on .aspx page load it calles the .ashx file for image reading. I am attempting to pass a session from the .aspx file to the .ashx file in order to make my query of grabing the image secure. The problem is that everytime I call a session: HttpContext.Current.Session["ID"], the value is returning null or errors saying the o so commong "Object reference not set to an instance of the object". I have tried a couple ways of grabing the session:
1.) context.Session["ID"]
2.) HttpContext.Session["ID"]
3.) HttpContext.Current.Cache["ID"]
none of them are giving me the ID session set in the .aspx page. should i be using Server.Transfer instead? is there a way to grab a session variable set in a .aspx page and called in a .ashx page?

I'm about to submit my pad file to multiple sharware sites but the pad file has to have a direct link to the download file and can't link to a download page which is what I would like to do, so I can track the traffic and get the downloader's email before allowing the download. I am running an ASP.NET site in VB. Is there a way to tell the web app to redirect to a specific aspx page when it receives a request for a specific file?

I am using a generic handler (indicator.ashx) to create a graphic that is overlayed from information from a table (called LIVE) from our SQL database. This is working very well and I am very happy with the results.
However I am having an undesirable issue where the query string that is used for this is also being accessed by another page (called ReceiveLive.aspx) which is populating our LIVE table with data when we don't want this. I have been able to track this issue down to our generic handler that seems to populate this table with data whenever the handler is accessed.
The query string that is used to access our graphic through our generic handler is
http://mydomain.com/indicator.ashx?ID=ABC001.
Our other page that writes data to our LIVE database used the query string
http://mydomain.com/live.aspx?ID=ABC001 which is normally only accessed by a small piece of software that sits on the users PC and sends the data when necessary.
My question is this: How do I prevent data from being written to our LIVE table via the Live.aspx page everytime a query string is processed by my indicator.ashx is accessed?

I create custom HTTP handler for auto generating file and I want to tell IIS7 to serve current request like normal static file because I need to use IIS and web.config file to control compression setting and any other HTTP header of current requested file.I know. there is an internal class called StaticFileHandler in ASP.net. But I cannot access it. Or you have any other way to work like this.

I 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 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 a form with a server side button, clicking on which session variable is added Session.Add("ABC","123")After this (in same postback event), I redirect user to a site, which returns user back to my site. And I still have session "abc" available to me.NOW, In another scenario I am trying to do the same thing but in a handler. I.e.User clicks a clinet side button which redirects users to sameSite.xyz. Handler of xyz adds session variable like above and redirects user to the other site. But, this time when user returns back from other site, my session is lost. How can I imitate scenario 1 with handlers?

I have 50 sites for 50 states. When a company uploads their contact info their image is stored in a folder relative to the site they are uploading from. When you view this company on the other sites the image is not present. So, I was thinking I would store the path of where the file is originally and then access it through the handler, but I can't seem to get the handler to recognize locations other than virtual directories.

a silverlight app sends an image to a webservice which store the image in a database and then a handler retrieves the image from the db to display it... quite common so far.
Everything is working absolutely fine on my test server (IIS on my development machine) but, as soon as i try it on the production server : no way, the image is never displaying (in any browser). Firefox says that it cannot display it because it contains error...
I tried to download the database from the production server just after saving an image to the db and, locally, the image is displaying...
The image is in png format.
