IHttpHandlerFactory registration

[AndyE]

ASP.Net experts :

Fairly new to ASP.net, and I'm struggling to register a custom handler
in the <httpHandlers> section of my application WebConfig file. At
runtime I persistently get the 404 not found error.

The syntax I'm using is :

<httpHandlers>
<add verb="GET"
path="Pooled.calc"
type="PooledHandlerFactory.PooledCalcFactory,
CustomCalcHandler" />
</httpHandlers>

"Pooled.Calc" is the URL requested from the calling web page

I have an C# IHttpHandlerFactory implementation named
"PooledCalcFactory" in a "PooledHandlerFactory" namespace. My assembly
dll is named "CustomCalcHandler"

I also noticed that if I comment out the registration entries for
IHttpHandler classes in the Web.config file, then I can't subsequently
re-register them (requests untended for these class result in the 404
error, wheras they were working prior to being commented out)

I've registered *.calc with IIS for the virtual directory in question,
and mapped it to the framework "aspnet_isapi.dll"

I'm using VS.net ver 7.0.9446
Framework ver 1.0.3705

Any pointers on where I'm going wrong ?

Many Thanks

Restart IIS.
And remove the *.calc association with aspnet_isapi.dll in IIS. Let the
framework handle it directly.

I've never needed to do this to register custom extensions in IIS.

And remove the *.calc association with aspnet_isapi.dll in IIS. Let
the framework handle it directly.
I'm not sure how this is going to help. IIS won't know how to handle the
..calc request. Which framework were you thinking of?

Which 404 page are you getting? Is it the default IIS 404 page or the ASP.NET
404 page? This tells you if the ISAPI is handling the request. Oh! This makes
me think that maybe you have the "Check that file exists" in your .calc ISAPI
registration. Make sure that the checkbox is not checked.

Make sure that you've mapped the correct ISAPI version if you have more than
one version of ASP.NET installed.

Thanks - the problem was that "Check that file exists" in the .calc
ISAPI registration was ticked - I suppose this makes sense, given that
none of my URL extensions resolved onto physical files.

Thanks !
