#1016: Increase http_resp_hdr_len and http_req_hdr_len (again)
 Reporter:  christian.albrecht  |        Type:  enhancement

Milestone:                      |   Component:  varnishd   
  Version:  trunk               |    Severity:  normal

 after upgrading to Varnish 3.0.1 from 2.1.5 I've noticed many 413 requests
 in varnishlog. The 413 requests are triggered by very long cookie headers.
 After some research I found your fix in Changeset
 d7c7c39abd8c56a7bce04991c7a8c35b58940dca (ticket #939). I manually
 increased the value of http_resp_hdr_len and http_req_hdr_len from 4096
 bytes to 8192 bytes. I have not seen any 413 requests since then.

 Is it possible to increase both values in trunk too?
