You can change the following lines in ext/unicorn/global_variables.h
and rebuild the parser:
DEF_MAX_LENGTH(REQUEST_URI, 1024 * 12);
DEF_MAX_LENGTH(QUERY_STRING, (1024 * 10));
There's currently no way to configure them otherwise, but I can consider
dropping these per-field limits entirely. We now have a config option
to set the maximum header size (only exposed via Rainbows!, though).
This means we would only care about the size of the entire header, and
not the size of any individual element. I consider the size of the
entire header more important anyways. We currently don't have
limits on the number of headers that can be sent.
