According to a very quick piece of research, you can use the $ENV{QUERY_STRING} in an executed SSI on Apache to pass information.

That is, if you have an include in your.server/mypage.html?page=1, the include "knows about" the "page=1".

This would allow you to pass information in a way, though it's not going to be neat.
