Muralidhar R Gondipalle

Hello All,
I have a doubt about when to use Http Module as against
global.asax. I understand that HttpModule is invoked before
global.asax. And also in web.config, why does the tab <add> tab in
<httpmodules> does not have a "path" like the one for <httphandlers>.

Thanks in advance,
Muralidhar

Thanx for the reply. I am not sure what additional events a HttpModule
can listen to. The only parameter to the init function is a
HttpApplication object and Global.asax is anyway derived from
HttpApplication. So I do not think it can listen to more events than
Global.asax

Thanx,
Murali

Doh!!!

You are correct. I was looking at the Global.asax and looked at the =
event
handlers that VS.NET puts in by default. Sorry if I mislead anyone.

That does bring an interesting point, since Global.asax Inherits from
HttpApplication, we can override the standard methods, or add some new =
ones.
You can't do that with an HttpModule...
