[horde] http headers on blank page on login

[Rick Emery]

Hi.

A friend of mine has an old CVS HEAD install running on his server. Instead of
trying to update to the most recent CVS HEAD, he decided to do a fresh
install.

When he tries to go to the login page, he gets a blank page with these http
headers:

Expires: Thu, 19 Nov 1981 08:52:00 GMT
Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0
Pragma: no-cache
Location: /hordenew/login.php?Horde=2c4d1678ae34b7b30fd7d2b37207936d
Content-Length: 0
Connection: close
Content-Type: text/html; charset=UTF-8

By copying and pasting the path (and session id) next to "Location", he gets
the login page. When he tries to login, he gets another blank page with http
headers, from which he copies and pastes the location and he gets his summary
page. From there, everything seems to work fine.

His logs only show a successful login; there are no errors in his web or horde
logs.

Has anyone seen this behavior before? Does anyone know what might be causing
it?

Thanks in advance
