How to redirect a folder to a subdomain?

[freemangl]

Eg:
I want to redirect
www.mydomain.com/wiki/***
to:
wiki.mydomain.com/***

how can I achieve that use .htaccess rewrite rule?

ps: 303 Redirect Type doesn't work in litespeed

Redirect 303 /wiki  http://wiki.mydomain.com

try rewrite:
in wiki/.htaccess:

RewriteEngine On
RewriteRule (.*) http://wiki.mydomain.com [R=303]

ah, thanks!

this works:

RewriteEngine On
RewriteCond %{REQUEST_URI} ^/wiki
RewriteRule (.*) http://wiki.mydomain.com [R=303]

It is better to create a wiki directory and put Rewrite rule or redirect directive in .htaccess under that directory.
The performance is better as the web server do not need to test it against every request, only when a request hitting wiki directory.
