On WAMP I need to redict each url specified in hosts file to a different localhost subfolder. How do I do it?

Hi all,

I use WAMP on Windows 7. In my localhost folder I have serveral sites and I would like to set several urls in the /etc/hosts file to ridirect me to different localhost folders.

Eg. I have already set the domain "www.mysite.com" to 127.0.0.1 in the hosts file.
Now when I type "http://www.mysite.com" I get redirected to the main localhost index/welcome page of WAMP.
However I have a folder called "mysite" and I would like to be redirected to that folder and not the localhost root.
I tried to edit the httpd.conf file by adding
Redirect permanent /mysite http://www.mysite.com
But this does not seem to work. I have also restarted wamp several times after having made this change.
Under my Apache the mod_alias is already on.

Could anyone suggest a working solution?

I have several sites and I need each one to be redirected to a localhost subfolder.

thanks in advance
