I needed to setup a catch all for one of my clients domains. This is what I needed to happen: If user typed in an incorrect sub domain for mydomain.com that did not exist I needed it to redirect them to www.mydomain.com. For example: if they type in notreal.mydomain.com it will send the user to www.mydomain.com. Here is what I did to accomplish this: Step 1: Added an A record to the mydomain.com domain zone of *.mydomain.com and had it point it to SERVERIPADDRESS. Step 2: Add ServerAlias www.mydomain.com *.mydomain.com to the httpd.conf file located in/usr/local/apache/conf/
