how to host mutiple domains in subdirectories of a main domain?

probably by httpd.conf ?!

[adrianTNT]

Hello.
I have a domain where I want to host more sites, like a parking domain.
For example fooparking.com...
How should the httpd.conf of fooparking.com look like if I want all my parked domains to show content from main domain?!

For example:
domain1.com will show contents from fooparking.com/domain1.com/
domain2.com will show contents from fooparking.com/domain2.com/
domain3.com will show contents from fooparking.com/domain3.com/

Any help is greatly appreciated, thank you.

This current thread [webmasterworld.com] addresses implementing this function in .htaccess, but the solution is easily adaptable for use in httpd.conf if desired.
