SERVER_NAME returns whatever apache has as the vhost's configured server name. the php manual says of HTTP_HOST: "Contents of the Host: header from the current request, if there is one." in which the last 4 words are a little off-putting. but: http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.23 i much more encouraging. the field is mandatory and should have what i'm looking for. it's absence is cause for a 400. casual testing (with a modern non-ie browser) seems to bear this out. so i'll try using that with fallback to my current techniques if i don't find a good value in HTTP_HOST. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
