112326 - Mozilla escapes URL's provided by Location header

Status: VERIFIED DUPLICATE of bug 110508

(Core :: Networking: HTTP, defect)

Description

[Andy Turner]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.6+) Gecko/20011118
BuildID:    2001111821

When Mozilla gets a Location header (at least, on a 302, I haven't tested with
other 30x responses) it escapes some (all?) invalid characters in the URL.  At
the very least it escapes all but the last question mark.

Reproducible: Always
Steps to Reproduce:
1.Go to http://turner.mikomi.org/moz/
2.Click on the Mozilla star.
3.See the 404 because Mozilla changed the first ? to a %3F.


Actual Results:  A final resting place of:
http://turner.mikomi.org/moz/index.html%3Fdumb=yes&url=http://turner.mikomi.org/moz/broken.cgi?x=42&y=34


Expected Results:  Other browsers (and even other versions of Mozilla) go to
this URL instead:
http://turner.mikomi.org/moz/index.html?dumb=yes&url=http://turner.mikomi.org/moz/broken.cgi?x=42&y=34

If Mozilla needs to fix the URL then perhaps later and not earlier
question marks should be escaped.

Windows IE 5.5SP1, Linux Communicator 4.7, and Windows Moziilla/20011112009 all
produce the expected result.

Duplicate of "doing SetSpec() with a string with a query doesn't do the right
thing".

This bug has been fixed since Nov 19, by the way.  So your buld just missed
it...
