Additional tips for custom proxy settings
In most corporate environments, your network administrator will provide a
URL for the PAC script.
The second most common configuration is that your network administrator has
set up a proxy server for accessing the public internet, but URLs on the
local network must be accessed directly. In that case set Proxy rules to
the URL of the proxy server (it may look something like
http://proxy.example.edu:port), and Proxy bypass rules to cover local URLs
(it may look something like *.example.edu,10.0.0.0/8).
If either of those apply, you can skip the rest of this guide. If not, we
document the syntax for Proxy rules and Proxy bypass rules below.
Proxy rules
A semicolon-separated list of protocolRules.
protocolRule -> [<protocol>"="]<URLList>
protocol -> "http" | "https" | "ftp" | "socks"
URLList -> comma-separated list of URLs, ["direct://"]
Some examples:
- http=http://foo:80;ftp=http://bar:1080- Use proxy- http://foo:80for- http://URLs, and proxy- http://bar:1080for- ftp://URLs.
- http://foo:80- Use proxy- http://foo:80for all URLs.
- http://foo:80,socks5://bar,direct://- Use proxy- http://foo:80for
  all URLs, failing over to- socks5://barif- http://foo:80is
  unavailable, and after that using no proxy.
- http=http://foo;socks5://bar-  Use proxy- http://foofor- http://URLs,
  and use- socks5://barfor all other URLs.
Proxy bypass rules
A comma-separated list of URIs. The URIs can be hostnames, IP address
literals, or IP ranges in CIDR notation. Hostnames can use the *
wildcard. Use <local> to match any of 127.0.0.1, ::1, or localhost.
