have created a HttpModule to do some preprocessing for a 
web
application. This preprocessing is to be done before each 
page of the
application is loaded. I have created a separate project 
compiled it and
added a reference to it in the web application. The code is 
working fine.
Now i need to deploy this ihhtpModule in the GAC. I have 
added the
following lines of code in the web.config file of the web 
application
<httpModules>
<add name="Authenticate" type="myModules.AuthModule, 
Authenticate" />
</httpModules>
where Authenticate is my dll name, myModules is the 
namespace and AuthModule
is the class name. This works fine when i use a local copy 
of the httpModule
but throws an error when i deploy the same in the GAC.
I ahve added these lines in the web.config file to refer to 
the GAC.
<assemblies>
<add assembly="Authenticate, version=1.0.0.0, 
Culture=neutral,
PublicKeyToken=d1a87f2cb11b878f" />
</assemblies>
Anybody with any idea as to how i can resolve this issue 
please help.

Thanks
