Validating a valid URL

[Shabam]

Is there a function that validates if a URL is valid or not? Basically I'm
trying to filter out bogus input, and things like cross site scripting
attacks.

Example:
<img src="javascript:alert(document.cookie)">

Doing it by regex seems way too complicated and there could be holes in the
logic if something is missed.

Shabam,

Your question is not new in dotnet Newsgroups, I did a search on Google
here are some, sorry using regex.

When that does not fit, I would ask it as well crossposted as you already
did in the newsgroups.
Microsoft.public.dotnet.languages.vb (or csharp) according what you use
and
Microsoft.public.dotnet.framework.aspnet

I hope this helps?
