Subject: Raise max header size to accommodate large tokens.
X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=aa1ba1f0176af286506e4188628e5acbb8f7f0e6;p=openstack-build%2Fcinder-build.git

Raise max header size to accommodate large tokens.

The max header is exceeded in the following scenario
- Auth tokens built with a keystone v3 API catalog
- A catalog with approximately 8 or more endpoints defined

An equivalent fix will be required for all projects which use
eventlet.wsgi.
