SUMMARY
Before this change the Host: header was runserver. Seems to be set by nginx upstream flow.
After this change we explicitly set the Host: header
More about CSRF checks ... CSRF checks that Origin == Host. Think about how the browser works.
"I'm executing javascript that I downloaded from awx.com (ORIGIN) and I'm making an XHR POST request to awx.com (HOST)" Server verifies; Host: header == Origin: header; OK!
vs. the malicious case.
"I'm executing javascript that I downloaded from google.com (ORIGIN) and I'm making an XHR POST request to awx.com (HOST)" Server verifies; Host: header != Origin: header; NOT OK!
