if i want to add a line such as "ServerAlias *.example.com" to my httpd.conf, but only to one domain on my server is this possible and where do I create the file?

for example full path to domain public_html is "/usr/home/***username***/domains/***userdomain***.com/public_html"

I'm guessing I just create a file named httpd.conf one level up from public_html but it's not working.


Thanks for any help on this =)
