I am trying to get Jira and Stash to talk to each other via a Trusted Application link.  The setup, currently, looks like this:
Jira - http - Jira Proxy -https- stash proxy -http- stash.
Jira and the Jira proxy are on the same machine.
The Jira Proxy is showing 403 Forbidden for POST requests from the stash server.  It works (or seems to ) for everything else.  I contend that since we're seeing 403 forbiddens in the access log for apache, Jira is never seeing the request.
Why is apache forbidding posts,and how do I fix it?
Note that the IPs for both Stash and the Stash Proxy are in the "trusted host" section.
