How to Apache Rewrite URL without redirect?

Question

Is it possible to replace a url name like http://mysite.com/sub/ with http://sub.mysite.com using htaccess?

I don't want to make a redirect rather than just to map a sub-directory address to a sub-domain address. So when a person types an address like http//sub.mysite.com/image.jpg this address remains in the browser but it reads the content from http//mysite.com/sub/image.jpg

Yes it is possible but you should have root access to the server to start with, you will need to also make some DNS record changes so ensure you have this access also before starting.

I have used both methods previously and they both work, however I found using folders was the winner at the end of the day for our usage, this simplified things significantly for us and we didn't have to worry about changing linkages in scripts, eg from http://www.my-site.com/images to http://images.my-site.com depending on the code structure being used.

Instead of typing these long instructions out I am going to give you 2 references that have slightly different approaches depending on if you have a physical folder to use or if it is a variable in the URL. They say it probably as well as I can anyway;-)
