You can use RegX to validate the text, or use the URI class.

You can use the Regex class to do this. I'm sure you can find something
useful at the below site that does it for you or gets you on the right path.

whether it *could possibly* be valid, or whether it *is* valid?
To get the regex for it, add a RegularExpressionValidator to a web project
and there's a pre-set list of regexes in there, one of them is a URL
template.
If you want to check if it *is* valid, then you'll have to send a request
and see if you get anything back.
