View 3 RepliesHow To Pass Through Http Call With HTTP Handler
Jan 4, 2011Background:
We are using the Facebook API and receive back URLs for profile image thumbnails. Unfortunately the protocol is restricted to just HTTP and it doesn't support HTTPS. The page on our site that hosts the thumbnails is always delivered via HTTPS, and if we use HTTP for the thumbnails the user will receive security warnings from their browser.
Solution:
Build an HTTP Handler that "passes through" the image from the Facebook URL, but allow the handler to be called via HTTPS. Before I started coding I thought I could something like this:
Response.OutputStream = WebRequest.Create(FacebookUrlForThumbnail)
but I ended up having to save the image to an object in memory than write the image to the Response.OutputStream using the image save function.
Current Code:
[Code]....
This seems inefficient but I can't find a way of using the HTTP Handler as I orginally intended. Is there way of accomplishing the goal without creating the image memory and just "passing through" the call?

View 2 RepliesHow To Catch Non-aspx Files With A Http Module
Sep 21, 2010If I make a http module it only catches .aspx files. Files with other extensions (.js, .htm) are ignored.
Does this have anything to do with IIS?
Strangely enough all extensions are caught on the ASP.net Web Development Server but not when hosted in IIS.

View 1 RepliesHttpHandlers / Modules :: Lowercase URL Rewriting With Http Module?
Jan 18, 2010Can anyone tell me if there is a way to convert all URL's to lowercase using an Http Module for URL rewriting? For example www.homeforhire.com/Home.aspx should be converted to lowercase.
I cannot use the IIS7 URL Rewriter because I need to perform database lookups as part of my URL rewriting.
I have researched this extensively but have not had any luck finding a solution.
The only alternative I can think of is to use a dynamically created canonical link in my page headers.

View 3 Replies.net - Use An HTTP Module Over Asp Health Monitoring Or Visa Versa?
Aug 31, 2010I have come across this question several times, you need to do some performance testing (request process times, load times, etc) or track unhanded exceptions.

Why would we use one over the other? What are the pros and cons?

View 2 RepliesGridView OnRowEditing Events Not Firing When Using Unity 2.0 HTTP Module?
Jan 31, 2011I have an ASP.NET web forms site using Master Pages. It is using Unity as my IoC container. I have created an HTTP Module to build up the container using a couple of tutorials i found online. I need the dependency injection to work for User Controls and the only way i was able to get this to work was to hook into the Pages PreInit event as can be seen from the code below.
[code]....
I also have autoeventwireup set to true on the pages and master page. Can anyone shed any light on why the events are not firing? Is my Unity http module causing this to happen by dropping the event wiring? I can get this to work no problem in a basic example with no IoC involved.

HttpHandlers / Modules :: Getting The Client Details In The Custom HTTP Module
Mar 16, 2011I am writing a custom HTTP module to implement user authentication and appropriate access rights.

Can we get these details from the HttpApplication or HttpContext object?
Configuration :: Default Page Not Working On IIS7 With URL Rewrite Http Module
Jan 18, 2010I have the following setting in my web.config to redirect to a default page:
<defaultDocument>
<files>
<clear/>
<add value="default.aspx"/>
</files>
</defaultDocument>
For example when a user enters www.homeforhire.com they should be redirected to default.aspx (for operational reasons the user is then redirected to
www.homeforhire.com/home.aspx).
Instead an error is caught in the Rewrite module (which should not be activated). I am using an http module to perform URL rewriting.
It appears as if the default document setup is not working correctly, and the requested page ~/ is being sent to the Rewrite module, causing an error (which is then caught by my error handler and the user is redirected to the home page).
Entering www.homeforhire.com/default.aspx works correctly.
Can anyone tell me why the default document settings in the web.config do not appear to be working?

Trying To Write An HTTP GET Handler?
Mar 24, 2011I'm trying to write an HTTP GET handler. The path should start with http://site/processTask and have a set of URL-encoded parameters. I have the following in my web.config
<httpHandlers>
<remove verb="*" path="*.asmx"/>
<add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
<add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
<add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" validate="false"/>
<add verb="GET" path="processTask*" type="MyHandler.ProcessTaskHandler, MyHandler"/>
</httpHandlers>
now when I type the URL http://mysite/processTask in browser I get HTTP 404 but if I change the add verb line to the following one:
<add verb="GET" path="processTask.asmx*" type="MyHandler.ProcessTaskHandler, MyHandler"/>
and type http://mysite/ProcessTask.asmx in browser the handler is run and I get the response from the handler. What's the problem? Why is the handler run only when the path contains .asmx? How do I change web.config so that .asmx is not required?
C# - How To Configure An Http Handler In IIS 7
Nov 24, 2010Here's what I want to do:
I've created a class library project
and this has a class implementing
the IHttpHandler interface. Let's
call this class ZipHandler. Let's
say the namespace is Zip.
I want that whenever any Http
request comes for a zip file, my
ZipHandler should handle it,
regardless of whether the request is
to an Asp.Net application or a
normal virtual directory.
Queries:
Is it possible (it should be given
the hype about integrated pipeline
etc. in IIS 7)?
How to do it?

Chart Control Needs An HTTP Handler?
Nov 25, 2010I have an VS2010 ASP.NET 4 web site app, to which I added the new Chart control.
When I deployed it to our web server, we get a" Internal Server Error 500." message.
I noticed that the following lines were added to the web.config since the last release, related to the chart control:
<system.web>
<httpHandlers>
<add path="ChartImg.axd" verb="GET,HEAD,POST" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
validate="false" />
</httpHandlers>
If I remove this added code from the web.config, the site works--Except for the charting functionality.
How do I get the site and the chart page to work?
This is not an issue on IIS versions < 7.
