I always called the "request string" the first line of the HTTP request, ie:
GET www.example.com?param1=val1&param2=val2param3=val3

There are no limits mandated by HTTP specs. By default Apache limits it to
8k; for it to be more you have to change compile-time arguments, but you
can lower the limit in normal config.

If you are trying to send a lot of data you need to use a POST, where the
size is virtually limitless (I think Apache 2 has an absolute limit of a
few gigs, but by default has a lower configured limit).

I have written javascript to do this using XmlHttp request for this project:
http://wikiwyg.org (use Firefox) which is GPL-licenced, so feel free to
gawk at the code. It sends a url-encoded POST, so the parameters are not on
the first line of the request.
