subfolder to subdomain help .....

hi:

     Is it possible to rewrite something like this:

https://www.domain.com/a/ to https://a.domain.com/  (eg. d:\www\a)

https://www.domain.com/a/b/c to https://a.domain.com/b/c  (eg. d:\www\a\b\c)

     and 

http://www.domain.com/a/b.php?info=c&test=d to http://a.domain.com/b.php?info=c&test=d 
(eg. d:\www\a\b.php)

http://www.domain.com/a/b/c.php?info=c&test=d to http://a.domain.com/b/c.php?info=c&test=d 
(eg. d:\www\a\b\c.php)

thanks for everyone!
