Your code appears to have come from GUI with HTTP::Daemon. A couple of lines prior to the one you cited is a line reading use CGI::Simple;. Do the Docs for CGI::Simple say about a res method? Do the Docs for other modules in the code sample talk about a res method or a res() function call?

This is a somewhat circumlocutious way of saying "It All Depends on the context, Grasshopper". You research the code, given the clues available, and determine the truth based on your discoveries.... (And don't forget that the "It's a Typo!" card is often played in code you find on the Web.)
