781995 - Location redirect issue with http://www.mozilla.org/

Status: RESOLVED INVALID

Description

[:Atoll]

While explaining DNS to someone, I found what *appears* to be a broken Location header in a 301 redirect for www.mozilla.org.  (Also, doesn't 301 mean that www.m.o no longer honors my browser locale?)

Location: http://www.mozilla.org/en-UShttp://www.mozilla.org/

The full telnet session is below, and I was able to reproduce it a couple times. I'm not able to get redirected to the broken URL in a browser, so it might only be an edge case for the bare minimum request such as what I sent over telnet:

:atoll the GET request you are submitting is a resource of http://www.mozilla.org/ so the response is as exptected. so the redirect returned would be the expected outcome.

i suspect what you intended to do was request the root resource (/)
