Interaction between httpmodules and httphandlers

In our asp.net 2.0 app we are using httpmodule and httphandler to calculate some metrics via cookies. To calculate network transfer time, httpmodule:EndRequest stores Transferstart in the cookie and httphandler:Processrequest uses datetime.now to subtract the transferstart to determine overall network time. Is this correct? I am also unclear about the request flow process. Does it go something like this: request > HttpModule::OnStart > HttpModule::OnEnd > HttpHandler::ProcessRequest?

Solution

  • The order is:

    • Module OnStart
    • Handler ProcessRequest
    • Module OnEnd

    By the way, it's probably better to use HttpContext.Items property to share info between a handler and a module instead of a cookie.
