Checking if web page exists

[Guest]

I'm building a web site and I need to link to an external page which at any
one time may or may not exist (server is not always on). What I need to do is
check before redirecting to this page whether it exists and if not go to a
different page internally which can explain that the external page is not
always available. Is there any way to check if an external page exists in
ASP.NET?
