There shouldn't be a limitation on the size, http 1.1 should allow any size as
long as the server manage that, otherwise you get an error message (nr 414?).
There are some old browsers that has trouble with the url length:
MSIE<3 url limit is 1k, MSIE3 2k
Seen mention of GET size limitations to 1024 - 2000, while POST should be
safer for big sizes.

session size is limited by the servers storage, but as soon as you have got
the data to the server it's there, no matter if you have session or not,
session is better for store data between scripts (switch from one page to
another).
