Change URL

Hello everybody,

for providing a secure access to our LimeSurvey-Studies, I am forced to change the URL from default, which obviousliy is the hostname, to any chosen name. Unfortunately that is the computing center's policy and there is no way, using the default hostname.

Example:
" HOSTNAME.SITE.de/limesurvey/index.php/survey/index/sid/XXX/ " should be changed to " somealias.de/limesurvey/index.php/survey/index/sid/XXX/ "

I've searched the "config-default.php" for any URL-Variable, but all I found, seem to refer simply on any file-locations.

Can anyone please give an advise, how to solve that problem?

Thank's in advance and best regards!
Simon
