Apache/IMP httpd.conf help?

[Rick Compton]

I need help with my httpd.conf config file.

I have installed IMP 3.0 and it works great except, all the links have
/horde/imp/ in the address bar. For example login appears as:

http://mail.my-company.com/horde/imp/login.php

Is there a way to tidy it up by removing the /horde/imp/ so the address
appears more simply as

http://mail.my-company.com/login.php


My httpd.conf is currently configured as

Alias /horde/ "/var/www/html/horde/"

# Virtual host mail
<VirtualHost 64.162.210.30>
 	DocumentRoot /var/www/html/horde/imp/
 	ServerName mail.my-company.com
 	ServerSignature email
	DirectoryIndex index.php
	Options None
</VirtualHost>

I am not sure why this doesn't work because from this

http://mail.my-company.com/horde/imp/login.php

should equal

/var/www/html/horde/imp/horde/imp/login.php

?????

Thanks.

Rick
