URL Rewriting and Sub-Domains

[icosytech]

Hi to all,

Here is my clarification in URL rewriting as a thread and hope this thread would turn into a great resource over the Web.

1. How to convert www.mydomain.com/folder/anyfile.php?user=xyz TO xyz.mydomain.com/anyfile.php?user=xyz

- Whether I need to create sub-domain for deploying the above?

Please give the right code to accomplish the above.

Thanks in Advance.
