Creating a filter for all text/html files

Hello, I'm working on moving a Web server to a new location, and to test it, I'd like to use a simple filter to replace all references to the old server name with the IP address of the new server. This is just for testing, so it's OK that it's not a perfect solution. Basically, I'm doing: s
