[rt-users] Lack of trailing slash causing porblems in IE

[Brendan Arnold]

Hi there,

When submitting form information such as logging in, updating a page
etc. Internet Explorer (6) returns a 'The page cannot be found' error
intermittently.

This happens consistently if I first load my RT login page as

https://example.com/rt

But not if I load it as

https://example.com/rt/

With the trailng slash. I think this may not be exclusively linked to
RT since there have been reports that similar intermittent problems
have been encountered with our Phorum installation (a PHP bulletin
board), however the problem with RT is much more frequent.

Some stats,

Solaris 9
Apache 2.0.55 (also happened with 1.3)
RT 3.4.5 (also happened with 3.4.2)
Perl 5.8.5
