Hey,

I just upgraded my system to OpenBSD 6.1 and have been running into problems with my Flask application deployed via uWSGI and FastCGI sockets.

Whenever I try to request the application I end up with a recursive redirect loop:

--2017-05-06 11:40:04--  http://foo.bar/
Resolving foo.bar (foo.bar)... x.x.x.x
Connecting to foo.bar (foo.bar)|x.x.x.x|:80... connected.
HTTP request sent, awaiting response...
  HTTP/1.1 301 Moved Permanently
  Connection: keep-alive
  Content-Type: text/html; charset=utf-8
  Date: Sat, 06 May 2017 09:40:04 GMT
  Location: http://foo.bar/
  Server: OpenBSD httpd
  Transfer-Encoding: chunked
Location: http://foo.bar/ [following]

As you can see I request the root path and get redirected to it. If I run uWSGI in HTTP mode without httpd in between, this does not happen, so I'm assuming it's not a webapp or uWSGI problem. Additionally, this worked
fine in 6.0.

Has something changed in the way paths are passed to FastCGI changed between 6.0 and 6.1?
