OK my main web server is Apache running of coarse, on port 80. My secondary web server is Personal Web Sharing, which must run on a different port. And oddly enough, PWS throws up errors, what seems like completely randomly, saying that you can't have double slashes or colons in the url, and display a 400 bad request error. But all you have to do is refresh and it works. It is the weirdest thing, does anyone know why this happens, and how to fix it?
Hmmm to clarify, the router is running 8.1 and PWS 1.5on 81, and it routes port 80 to my G4 which runs apache.
