Luca Rea commented on TS-3212:
------------------------------
The headers have been captured with firebug so the IMS header has been added in
the request from the browser.
I suppose the behaviour of ATS is correct, here the bug is that cache.config
doesn't permit to skip IMS, the object is considered cachable and ATS returns
always the rewritten 304 code instead of the original 200 (I've tested
url_regex without success).
The only way to force ATS to forward request to origin is disabling
"proxy.config.http.cache.cache_urls_that_look_dynamic".
> 200 code is returned as 304
