web sharing for vhosts?
Yes, you can configure Mac OS X 10.7, aka Lion, to serve multiple web sites using URLs like http://[my-local-ip-address]/~mytestsite.

The format of URL you suggest can be achieved by creating a new user for each site, and storing the web pages in that user's Sites folder.

Alternatively, you could create subfolders within your site's folder:


http://[my-local-ip-address]/~[myusername]/site1
http://[my-local-ip-address]/~[myusername]/site2
http://[my-local-ip-address]/~[myusername]/site3


Going another step further, you can customise the Apache httpd 2 configuration files at /etc/apache2/users/[myusername] to tweak the set up to your exact needs.
