How do I force the browser to update its base URL

Question

I have a PHP script that uses CURL to fetch a remote page and return the output as is. It displays fine in the browser, but the problem is, when I click a link it is still using the old base url. Can I force the browser with some kind of HTTP Header or something to use the base url of the server that I fetched the page from in my PHP script?

Answer 1

If you can inject into the source you could use a base tag and set the href to the base page you want to use.

Answer 2

So do not output it as is, parse and replace URL and only then output it.
