使用.htaccess将流量重定向到同一域

Question

Well it's kind of hard typing a title to describe what I want to do.

Basically I have a website that I've been asked to develop a mobile site for. This website has various domains (such as .co.za , .com , .za.net ) but they all run from the same folder on the server (so I only have one .htaccess file).

I want to be able to redirect the traffic that goes to www.example.co.za to m.example.co.za and traffic that goes to www.example.com to m.example.com .

How would I need to modify this .htaccess file to achieve that.

RewriteEngine on
RewriteCond %{HTTP_USER_AGENT} "alcatel|amoi|android|avantgo|blackberry|benq|cell|cricket|docomo|elaine|htc|iemobile|iphone|ipad|ipaq|ipod|j2me|java|midp|mini|mmp|mobi|motorola|nec-|nokia|palm|panasonic|philips|phone|playbook|sagem|sharp|sie-|silk|smartphone|sony|symbian|t-mobile|telus|up\.browser|up\.link|vodafone|wap|webos|wireless|xda|xoom|zte" [NC]
RewriteRule ^$ http://m.example.com/ [L,R=302]

How about:

RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} "alcatel|amoi|android|avantgo|blackberry|benq|cell|cricket|docomo|elaine|htc|iemobile|iphone|ipad|ipaq|ipod|j2me|java|midp|mini|mmp|mobi|motorola|nec-|nokia|palm|panasonic|philips|phone|playbook|sagem|sharp|sie-|silk|smartphone|sony|symbian|t-mobile|telus|up\.browser|up\.link|vodafone|wap|webos|wireless|xda|xoom|zte" [NC]
RewriteCond %{HTTP_HOST} ^(www\.)?(.*)$ [NC]
RewriteRule ^(.*)$ http://m.%2/ [L,R=302]
