I seriously suggest you try your hardest to avoid altering the actual
content. Altering content directly gets you straight into a minefield of
legal issues with the copyright owners of said web content.

Splash pages are accepted by most clients in this type of situation.
Which periodically cut the viewing process into a full page of advert
with a continue link back to the previous request. Look into captive
portals for how to do this in an easy way with any squid-2.6 or later:

Doing anything with the body in Squid requires a separate ICAP service
or eCAP plugin written specifically to perform the act. This requires
squid-3.0 pr later (the newer the better).

You might get away with the frame trick since the original content is
still available unchanged. Though browser support for frames is a very
confused area with frame, iframe, script, embed and object all doing the
same role depending on the browser if it supports sub-frames at all.
