Can i forward users based on the domain theyve come through

[Vini]

I have a few domains all on one hosting.

Based on the domain name they type, can i forward them to root.com/domain/ via htaccess?

[Moby-Dick]

isn't that a host header thing ? ( in IIS anyways )
I seem to remeber apache supports it to, with virtual roots ?

this is separate from all my other q's this is my personal webspace, with which i dont have much control, only HTaccess

You have scripting support on the host?

In ASP you can do a server-side redirect, for example.

[Richard Loxley]

If you have server rewriting rules activated on your hosting (e.g. mod-rewrite in Apache) you can do this via .htaccess.

An example from my website for supporting multiple sub-domains:

RewriteEngine On
RewriteBase /

RewriteCond %{HTTP_HOST} example.co.uk$
RewriteCond %{REQUEST_URI} !default
RewriteRule ^(.*)$ default/$1

RewriteCond %{HTTP_HOST} www.example.co.uk$
RewriteCond %{REQUEST_URI} !default
RewriteRule ^(.*)$ default/$1

RewriteCond %{HTTP_HOST} richard.example.co.uk$
RewriteCond %{REQUEST_URI} !richard
RewriteRule ^(.*)$ richard/$1

RewriteCond %{HTTP_HOST} david.example.co.uk$
RewriteCond %{REQUEST_URI} !david
RewriteRule ^(.*)$ david/$1

This directs all requests for the main website to the "default" directory, and the sub-domains "david" and "richard" to respective directories.

The rules are applied recursively, so each of these rules is basically saying: "if the domain they've typed is richard.example.co.uk, and the filename they've asked for doesn't start with richard, then add "richard/" to the start of the filename. You need the check that you haven't already added the directory prefix, otherwise it will create an infinite loop! I found this the hard way :-)

Do a search on google for URL rewriting via .htaccess, or give us some more detail about what exactly you want to achieve and I'll try to help :-)
