Yes of course. You need to translate all links in the HTML to point to the
proper _absolute_ server_B-page. If that is at all possible with that simple
means (you might need to pass-thru/translate things like cookies too, which
easily could become a mess).

Possibly, you translate all links in the page to go through a proxy-script on
server A that automatically gets the correct page from server B and displays
it to the client.

It could handle all cases, if you just write your translator good enough.

If you need to do this (getting the page from serverB and showing it on
serverA), I can't see how you can avoid this step.

Your problem is obviously not the fetching of the page, which curl does and
is a suitable tool for. Your problem is that you need to translate URLs/links
in a HTML page to make them go through a script at your site or to the
absolute pages of the second server.

That is not anything curl can help you with. Curl gets the page for you. You
do the rest.
