Doubts about the Apache2.2 server configuration multi-site

Questions about configuring multiple sites for Apache2.2 servers
That's it, my local machine, there are several independent websites,
I now want to implement input: HTTP://127.0.0.1/WEB1, open Web site, http://127.0.0.1/web2, open Web2 website,
In Apache2.2, how to configure?

Online to find the next, are some of the multi-domain AH configuration What, these simply useless, such as the following:

DocumentRoot E:\www\discuz\bbs
ServerName bbs.xxxx.com

Second virtual host, specific parameters to modify their own

DocumentRoot e:\www\site//directory where the second virtual host is located
ServerName www.xxxx.com//Domain name


It is not easy to understand, you configure two domain names, you can open two local sites?
Apparently not, all of them went to the Internet.
I would like to ask you prawns, I exactly how to configure to achieve:
Input: http://127.0.0.1/web1, open Web site, http://127.0.0.1/web2, open web2 site, the function of it?
Just contact with PHP, it is troubled by this problem ....

------Solution--------------------
It is the configuration of the virtual host, you obviously do not need, just put the BBS and site directory into the root directory.
------Solution--------------------
OK. 127.0.0.1 is pointing to the Apache root directory, to implement other drive-letter access, please refer to the above notation. You can also search the "Configure Apache Virtual directory" method on the Web.
