Hi Guys
I have a problem with my httphandler here. I have several httphandler in my
application. each of them do the different job. but I found sometimes it
really slow down the performance. Is there a way I can specify that one
handler can only be used on certain pages? like httphandler A is used on
page A,B and httphandler B is only used on Page C, D?

Cheers
Victor
 
Hi Victor,

From your description, what you wonder is how to make each registered
httphandler only serve a certain set of requests/pages, correct?

Based on my understanding, you can consider the following two approaches
here:

1. Since custom httphandler or httpmodule setting can be configured in sub
directory level, you can consider group those pages or requests in to
different child directory of your ASP.NET application and configure the
specific httphandlers in those sub directory's web.config file. Thus,
requests to one sub directory won't be able to use handlers registered in
another sub directory.

#<httpHandlers> Element
http://msdn2.microsoft.com/en-us/library/aa903367(VS.71).aspx


2. Another formal way is use a HttpHandlerFactory, you can register this
factory as handler in your web.config for all the requests. Then, in the
handlerFactory's code, you can check the coming requests(url or other
conditions) and determine which handler to return and process the request.

Hope this helps.

Hi steven..Thanks for help..
but I have found i made a stupid mistake. I am using a httpmodule instead of
a httphandler.
What i want to achieve is i have a httpmodule to handle my uploade file
function. But I want this module will only be used when there has something
want to be uploaded to the server. Currently, all pages need to go through
the beginrequest method for the upload httpmodule.
is there anyway I can avoid this?

Thanks
Victor
 
Thanks for your followup Victor,

So you're actually using the httpmodule. If so, I think this is the
expected behavior. According to ASP.NET server-side processing pipeline
model, each ASP.NET requests will come through those httpmodules registered
in the application(there is no filter to exclude specific requests). If you
do need to use httpmodule and ignore some particular requests(depend on the
url's extension), you should manually check the request url in httpmodule's
code).
