apache2 - how to increase Apache 2 uri length limit

Question

I am getting this error in my apache2 log:

[Tue Apr 06 09:00:56 2010] [error] [client A.B.C.D] request failed: URI too long (longer than 8190)

What setting can I change to increase this limit?

Answer 1

The best answer is "don't do that". See https://boutell.com/newfaq/misc/urllength.html (link goes to Internet Archive backup) for an explanation of why.

If you need to pass that much data, use POST, not GET.
