This is not going to happen sorry. Unfortunately there are too many
points in the code allocating buffers for URLs which do not use the
MAX_URL definition.
For example; I am this very minute testing a patch to remove one more of
those bits of code I just found trying to stuff a 8KB URL into a 4KB
buffer :-(.

We have an ongoing project to remove the URL length limits from within
Squid. Hopefully that will resolve the issue as it progresses without
the need for a config option. If you are using Squid-3.5 you may see a
reduction of these messages from Squid-4.


PS. Squid is known to be one of the most lenient web agents. Most origin
servers and other proxies have smaller URL restrictions. So whatever
application is trying to use >9KB URLs is unlikely to work generally
over the Internet even if we resolve the Squid complaints.
