How to add a subdomain ?

["support logisphere.net" <support@xxxxxxxxxxxxxx>]

Hello,

I'd like to add a sub domain to my squid server (this is only for tests).

Then I added to the squid.conf the line :

acl accelerated_urls urlpath_regex /subdomain.mydomain.com (plus all my 
domains ...)

Where I try to reach my subdomain I get an access denied, the url I use 
is "http://subdomain.mydomain.com";. How can I add this subdomain ?

I'm using Squid 3.0 PRE3 20060307

Thanks,
Sebastien
