Converting Relative to Absolute URLS

How?

[raingerpete]

hi,

Does anyone have a script to change relative URLs to absolute ones?

The URL is given within a web page.

But I have realised the $rel_url can be :

"../../some.css"
"dog.css"
"/mars/ish.css"

and its not just a case of apending the url onto $web_page_url .
