Subject [users@httpd] Re: Http trailers in chunked requests
Date Mon, 20 Jul 2015 06:14:37 GMT
Hi Eric,

We are using mod proxy and mod rewrite to forward the request to an haproxy
server running a pool of tomcat. I have verified that when the request is
directly sent to haproxy, trailers are sent to the tomcat and it does print
it in the debug logs.

While debugging this I have also noticed that apache converts a chunked
request < 8KB to a non chunked one and assembled the whole body before
sending it down the proxy.

Thanks
Sachin

Sorry could not figure out how to post from a digest, I have copied your
question below:

>> What module handles this request, and where are you looking for the
trailers?
