How do I check entered URL is valid or not

Hi Abhishek,

I already added customError in web.config. but when user add URL like http://www.abc.com/test.aspx/xyz in this case it's not hitting filenotfound.aspx.

Note: http://www.abc.com/test.aspx is valid URL.

I tryied secound solution given by you in global.aspx application_authenticateRequest and
application_beginRequest also. but application will hanged. after using (var response....) line cursor goes to application_authenticateRequest and then using (var response....) line till application hanges

Please suggest what else I need to do.

You can check it in the Global events in Global.asax file, like BeginRequest Event.

One more way is to add entry for this in Web.Config;

are you reading this url value from a textbox in your application or just want to check directly in browser?
