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.

Re: Validating a valid URL

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.publi c.dotnet.langua ges.vb (or csharp) according what you use
and
Microsoft.publi c.dotnet.framew ork.aspnet

I hope this helps?
