We are observing a very strange issue with Apache 2.2.14 serving as a transparent proxy to an application server using mod_proxy, when the application server sends chunked mode response
Apache is listening over SSL & reverse proxying to the backend server HTTP, We have SSLProxyEngine & SSLEngine set as on
things work well when the response is not chunked mode encoded, but Apache seems be broken when the backend sends gziped content over chunked mode transport
Unfortunately we don't control the backend server to enforce HTTP 1.0 on it

We have tried to upgrading to the latest release Apache 2.4 using OpenSSL 1.0.1 with no success, any thoughts on what might be wrong here
