asp.net handler not picking up case sensitive - asp.net

I have this handler in my web.config:
<add name="handler1" path="*.jpg" verb="*" type="ImageHandler" resourceType="Unspecified" preCondition="integratedMode" />
Problem is the path is case sensitive. I want this handler to also pickup path like *.JPG. Is there any way to make the above line case insensitive?

As a quick fix, you can have a copy of this handler with path="*.JPG"

Http handler is not getting called in asp.net?

I have website which I opened in Visual web developer express.
In web.config , I have a handler defined B.
<add verb="GET,POST" path="*/faq*" validate="false" type="DefaultRedirectHandler" />
How to specify the location DefaultRedirectHandler which is a dll in this environment?
I created a handler.dll which contains the class B derived from IHttpHandler in bin directory but there are signs it is not used.
Also, I tried
<system.webServer>
<validation validateIntegratedModeConfiguration="false" />
<handlers>
<add name="ASP Wild" path="*" verb="*" modules="IsapiModule" scriptProcessor="C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" resourceType="Unspecified" requireAccess="None" preCondition="classicMode,runtimeVersionv4.0,bitness32" />
<add name="SampleHandler" verb="*"
path="*"
type="DefaultRedirectHandler,handler.dll"
resourceType="Unspecified" />
</handlers>
Is there some log I can look at if this handler is called elsewhere.
When you add your handler you should fully qualify its type. Include the namespace along with your type name.
<httpHandlers>
<add verb="*" path="*"
type="MyHandlerAssembly.With.A.NameSpace.IISHandler1, MyHandlerAssembly" />
</httpHandlers>
How to: Register HTTP Handlers
The assembly your handler is in must either exist in your web application's bin directory or the system assembly cache.
For more details on the configuration for HttpHandler's see the following.
add Element for httpHandlers (ASP.NET Settings Schema)
Keep in mind that there are many ASP.NET handlers added by default and defined by the system machine.config and root web.config (in your .NET library directory). If any of these handlers match your path they could be executed first. If they close the response then your handler may never get executed.
EDIT:
As for debugging what is going on on your server (i.e. what handlers in what order are getting called) you may be interested in checking out Glimpse.

Open Links via HttpHandler

Please help with HttpHandler
There is a HttpHandler that handles links to mysite.ru.
Registered in Web.Config as follows:
<configuration>
<system.web>
<httpHandlers>
<add verb="*" path="mysite.ru" type="App_Code.SyncHttpHandler"/>
</httpHandlers>
</system.web>
</configuration>
Now through the Handler open only references of the form:
mysite.ru
mysite.ru/struct/
mysite.ru/articles/
How to make the handler to intercept and treatment on the links of the form:
mysite.ru/files/images/img.jpg
mysite.ru/files/scripts/script.js
If I write so that you can run any links, including SyncHttpHandler/Google.ru.
And I need to be able to run only links a specific site.
<add verb="*" path="mysite.ru/*.*" type="App_Code.SyncHttpHandler"/> don't work
<add verb="*" path="*.*" type="App_Code.SyncHttpHandler"/> open any links
<httpHandlers>
<add verb="*" path="*.js" validate="false" type="SyncHttpHandler" />
<add verb="*" path="*.jpg" validate="false" type="SyncHttpHandler" />
</httpHandlers>
you can use this.
Typically, IIS process all static files by its own static file handler. So you need to first configure your IIS to pass all files (extensions) under this path to ASP.NET run-time. Exact steps (although similar) will depend upon IIS version - for example, see here for IIS 6.
Next part would be making sure that ASP.NET runtime passes all those requests to your handler. As such, I think that your config should work but if it doesn't then try using wild-cards. For example,
<add verb="*" path="mysite.ru/*.*" type="App_Code.SyncHttpHandler"/>
or perhaps,
<location path="mysite.ru" >
<system.web>
<add verb="*" path="*.*" type="App_Code.SyncHttpHandler"/>
</system.web>
</location>

Wildcard HttpHandler not handling Static Files

I had a look through some of the older questions, but I can't find anything.
I have a Wildcard HttpHandler on my web app which is processing the url and working out if it can do anything with it
If it can't, then the StaticFile Handler should pick it up and just serve it as a static file (like an html file).
The problem is, it's going through the Wildcard handler, then seemingly not going to the StaticFileHander. Is there something I need to do to the Wildcard handler, or in the web config?
This is my web.config:
<add name="Wildcard" path="*" verb="*" type="Rewriter.RewriterHttpModule"
modules="IsapiModule" requireAccess="None" allowPathInfo="false"
preCondition="" responseBufferLimit="4194304" />
<add name="StaticFile" path="*.*" verb="*"
modules="StaticFileModule,DefaultDocumentModule,DirectoryListingModule"
scriptProcessor="%windir%\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll"
resourceType="File" requireAccess="Read" allowPathInfo="false" preCondition=""
responseBufferLimit="4194304" />
Perhaps your HttpHandler should pass off the request to the StaticFileHandler explicitly.
To follow up on what Hunter said, yes, perhaps add this entry to your Web.Config following the first wildcard mapping:
<add verb="*" path="*" type="System.Web.StaticFileHandler" />
Just a thought. Haven't tested this or anything.
Check the application pool pipeline mode. If it is Classic than you have to configure your handlers in the <httpHandlers> section. If it is Integrated you should use the <handlers> section in web.config.

Can you use relative paths when registering handlers in web.config

I need to register a httphandler in a sub folder ("myTest") to my web application.
I know that a solution would be to add a webconfig to the myTest folder, but that is not an option in this case.
I would like to add the following to my web.config (focus on the path attribute)
<system.webServer>
<handlers>
<add name="myHandler" verb="*" path="myTest/myHandler.axd" preCondition="integratedMode" type="xxxxxx.xxxx, xxxxxx" />
</handlers>
</system.webServer>
IIS 7 doesn't complain about the relative path, but it doesn't work either
Another option would be to just place and .ashx file in the folder. Then you don't need to register anything in web.config.
The path attribute shouldn't point to the handler itself, but specify the paths affected by that handler. So in your case:
<add name="myHandler" verb="*" path="/myTest/*" preCondition="integratedMode" type="YourHandlerAssembly.YourHandler, YourHandlerAssembly" />
Should pass all files in the myTest subfolder to your HttpHandler.

HTTPHandler tag in Web.Config breaks asmx Files

In my ASP.Net 1.1 application, i've added the following to my Web.Config (within the System.Web tag section):
<httpHandlers>
<add verb="*" path="*.bcn" type="Internet2008.Beacon.BeaconHandler, Internet2008" />
</httpHandlers>
This works fine, and the HTTPHandler kicks in for files of type .bcn, and does its thing.. however for some reason all ASMX files stop working. Any idea why this would be the case?
Cheers
Greg
I got it... CQ you were on the right track.. i did need to add the .asmx handler again, but the .net 1.1 specific one. Final code is as follows:
<httpHandlers>
<add verb="*" path="*.bcn" type="Internet2008.Beacon.BeaconHandler, Internet2008" validate="false" />
<add verb="*" path="*.asmx" type="System.Web.Services.Protocols.WebServiceHandlerFactory, System.Web.Services, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" validate="false"/>
</httpHandlers>
I hope there's no other file types that are not getting handled properly because of this declaration. :|
Thanks for the help
greg
It sounds like it as an inherant <clear /> in it although I don't know if I've seen this behaviour before, you could just add the general handler back, let me find you the code.
<add verb="*" path="*.asmx" type="System.Web.Services.Protocols.WebServiceHandlerFactory, System.Web.Services" validate="false">
I think thats the right element, give it a shot.
EDIT: That is odd, I don't have a copy of 2003 on this machine so I can't open a 1.1 but I thought that was the right declaration. You could try adding validate="false" into each element and see if that makes a difference.
