Javascript .pac file

Question

Is there a way to get a browser to read a .pac file without having the user manually point the browser's automatic config file at the URL?

Answer 1

Are you talking about Proxy Autoconfiguration?

Basically you have to configure a host name such as wpad.example.com and put the file there named as wpad.dat
