Status: VERIFIED DUPLICATE of bug 110508

(Core :: Networking, defect)

Description

[Neil Pryde]

I keep getting errors trying to read my e-mail, with build 2001111708, but prior
versions seems to work well.

Steps to reproduce:
1 - visit www.netscape.net
2 - click on the e-mail button
current result:

Not Found
The requested object does not exist on this server. The link you followed is
either outdated, inaccurate, or the server has been instructed not to let you
have it.

expected result: load page

NOTE: I do get a bunch of strict warnings (line 1189) and one JS error (line
1294) on the JS console.

Forget about that error on line 1294. This error is caused by the MultiZilla
popup blocker, I don't see this error when I disable the popup blocker in the
QuickPref menu.

note: I just did a second test without MultiZilla installed, but still the same
problem, unable to read my e-mail.

URI parsing.

The "Mail" link redirects to a url of the form:

http://foo.netscape.com/bar?baz=quork&aaa=http://somewhere.somehow.com/file?c=d

Notice the presense of the two "?" characters.  Mozilla escapes the first one of
these, which causes things to break.  (the request is made to 
http://foo.netscape.com/bar%3Fbaz=quork&aaa=http://somewhere.somehow.com/file).
Escaping the second one instead works.

Netscape 4 seems to escape neither one, and therefore treats this as a request
to http://foo.netscape.com/bar which works.
