hello, i have a free host: http://beijinggifts.zxq.net/;

and i add a custom domain:changanyezhu.com , also i add the sub domain www.changanyezhu.com.

now, i meet a big problem: www.changanyezhu.com will turn to changanyezhu.com automatically. and it is in 302 style.

how should i do?

by the way: dns of changanyezhu.com is * ns1.zxq.net * ns2.zxq.net

Normally, "http://www.example.com/" is not treated as a subdomain. Even though the visitor is using "www" as part of the address, our servers will not look for a directory named "www" and try to use the files it contains. Instead, our servers will use the files at the top level of your site. This makes sure "http://example.com/" and "http://www.example.com/" are handled identically, which is almost always what you want to happen. I believe this is also the case even when you use 302 style. It's recommended that you use another subdomain instead.
