             Summary: Make various header sizes configurable (instead of fixed)
                 Key: TS-2809
                 URL: https://issues.apache.org/jira/browse/TS-2809
             Project: Traffic Server
          Issue Type: New Feature
          Components: Core, HTTP
            Reporter: Leif Hedstrom


It'd be swell if [~amc] could make some of the currently static buffer sizes runtime configurable. Ideally even overridable. For example

{code}
proxy/hdrs/HdrHeap.h:#define HDR_HEAP_DEFAULT_SIZE   2048
proxy/hdrs/HdrHeap.h:#define HDR_STR_HEAP_DEFAULT_SIZE  2048
proxy/http/HttpSM.h:#define HTTP_HEADER_BUFFER_SIZE       2048
{code}


There might be several others :). I imagine a site using ATS could have some reasonable knowledge of their typical header sizes, and size these accordingly for optimal performance.
