Description of problem:
In certain cases, gears need the ability to tune the maximum HTTP header size so that large HTTP headers can pass through to the receiving server (e.g. JBoss).

The specific variable that gears need to be able to control is 'tune.bufsize', and it must be increased from the default so that large objects can be passed through (e.g. x509 certificates) via the  X-Forwarded-SSL-Client-Cert header.

We have determined that 216000 is appropriate for our application, but we cannot say whether or not this value is appropriate for *all* applications.

Version-Release number of selected component (if applicable):
All

How reproducible:
Send a large HTTP header above the HA proxy default.


Actual results:
Connection is dropped.

Expected results:
Header is passed
