I think you have to use a proxy because that's how WFS works, that will end up making any request you use through openlayers go through a proxy also. I am sort of new to openlayers as well and just figure stuff out from their examples and experimentation. I just plug in urls in openlayers to my rails server and then see what kinds of requests openlayers sends out that come out in the console or log and try to figure out how to handle them etc. They have some examples on the proxy. I think they have a perl cgi example. What is your web server ? Are you use PHP, Java, etc ?
