Comment 10 for bug 1518431

It took some amount of time to debug this issue for Glance.
It turned out that both Glance and Swift support chunked requests. Unfortunately, chunked uploading is not supported mod_fastcgi that is used by RadosGW. It is very typical for Apache to response with 411 error because some cgi (or wsgi) frameworks always require Content-length to be specified.
Request with transfer-encoding=chunked is a part of Http spec so glance_store prepares correct request here.
So I would recommend to deploy RadosGW under different CGI (for example mod_proxy_fcgi) that supports chunked requests.
I will mark this as Invalid for Glance, please re-open the bug if you don't agree.
