So I’m working on a large rails app that has a bunch of selenium tests. Running a local dev instance of the site (apache w/ mod_passenger) works fine, but when I run the selenium test suite I get a bunch of failures, particularly on re-directs. The HTTP response header comes back poorly formatted. Among other problems the
Set-Cookie header key seems to have been deleted and only the value appears.
PS: I have already solved this problem, just posting the question / answer for the community to see.
