How can I redirect requests based on host?

[Jay Shen]

Hi,

I have two domains pointing to the same ISP hosted web site.
How can I redirect request for www.domain2.com to a sub-folder using header
field "host"?
Thanks a lot...

In your index file:

if (ereg("domain2. com", $_SERVER['HTTP_HOST'])) {
header("Locatio n: /subfolder/");
}

After that of course you'll have to make sure all your links include the
subfolder path.

I've heard that some browsers have trouble with the Location header if you don't
include the full url, but I'm not sure if which ones. You might want to try:

header("Locatio n: http://www.domain2.com/subfolder/");

Surely your ISP can set up name-based virtual hosts under Apache?

The field value of the Location HTTP header must consist of an
absolute URL; a relative URL would contravene RFC2616, sec. 14.30.
Resultantly, relying on relative URLs working is unwise, despite
applications supporting them.

Re: How can I redirect requests based on host?

Similarly, if you're running Apache, you can do this without having to worry
about links by using mod_rewrite and checking what the hostname specified in
the URL was. Check out the documentation for mod_rewrite:

http://httpd.apache.org/docs/mod/mod_rewrite.html (Apache 1.3)
http://httpd.apache.org/docs-2.0/mod/mod_rewrite.html (Apache 2.0)

Hope that helps.
