[horde] traces in apache error_log about impattxxx for file_get_contents and Compose.php

[LALOT Dominique]

Humm..

Looking a little bit further, I discovered that the temp file was not
written on the good server!

I have to explain that horde is load balanced through apache2.2
mod_proxy_balancer and mod_rewrite (to add a cookie with the route).
I noticed some problems with directory redirections not working properly as
the real host was used instead of the load balanced host. So the cookie was
not sent.

In my conf.php, server name points to the load balancer:

$conf['server']['name'] = 'horde.univ.fr';
if somewhere, the real host given by apache is used, that can explain why,
the temp file is created on a random server, then read on the good server,
but unreachable..
