I've got a site that has a large form that I split up into several pages. I'm using php sessions to gather data as the pages go along. The trouble is, though, that there are many many fields. After I get about 4 pages in deep out of 5, I get this error:
Your browser sent a request that this server could not understand.
Size of a request header field exceeds server limit.
I'm also using cookies to keep track of data, so that if a person returns, they will be able to have all the fields pre-filled. Suffice to say, quite a large sum of cookie strings. I'm serializing all the data, so there aren't many cookies, but quite a bit of data in each cookie.
Is there a setting on the server to adjust to increase the size or another way around this issue?
