This PAC file uses a white list, which contains websites that can be directly accessed. If some domains are not included, they will access through the proxy.

If you use this PAC file, you may need a proxy which not bill with the flow.

This white list comes from felixonmars dnsmasq-china-list

Switch to the gh-pages branch to download the latest pac file!

Download the whitelist.pac, and edit the server IP and the proxy type. After that, change your browser's config, and point to whitelist.pac.

var proxy = new Array( "SOCKS5 127.0.0.1:1080; SOCKS 127.0.0.1:1080;",
Change the type of proxy, it also can be 'HTTPS'
Make sure to change both SOCKS5 and SOCKS

Execute command python3 main.py, whitelist.pac will be updated.

You can change the okToLoadBalance value to true to use the load balance feature. When you edit whitelist.pac, you will find three proxy configs in there. Only the first config will become effective if you leave okToLoadBalance maintain false, but if you want to use load balance, you need to edit all of the proxy row as well.

"SOCKS5 127.0.0.1:1083; SOCKS 127.0.0.1:1083;",
Different port or IP, and do not lose the comma!

As you see, proxy is an array. You can add at most ten proxies to load balance! Though three is good enough.

There is one more thing you should know that load-balancing is domain-based load balance, so it would not accelerate video or download something. Do not use this feature if your proxies are not speed the same.
