ses.setProxy proxyRules don't allow proxy bypass configuration

[tejohnso]

proxyRules = schemeProxies[";"]
schemeProxies = ["="]
urlScheme = "http" | "https" | "ftp" | "socks"
proxyURIList = [","]
proxyURL = ["://"][":"]

ses.setProxy takes a PAC script, its easy to specify proxy bypass configurations there. Is there a reason for not using PAC script ?

[tejohnso]

I dont know the rules ahead of time. It seems kludgy to have to provide a URL to a file that contains a dynamically generated JavaScript function as a parameter to a JavaScript function call. But if it's the only way I'll give it a shot.

hmm we can add a proxyBypassRules option.

As listed in the examples of the ses.setProxy API, direct:// represents for no proxy:

http=foopy,direct:// - Use HTTP proxy foopy for http URLs, and use no proxy if foopy is unavailable.

@zcbenz I believe the OP wanted certain hosts to bypass proxy while not others, this cant be achieved with proxyRules while certainly can be achieved with a PAC script but since the OP wants to dynamically specify the rules, PAC might turn out useless.

@deepak1556 The ProxyConfig of Chromium is not able to set proxy rule per host as far as I know.

The PAC script can be set dynamically, users can always generate a PAC script on the fly and then save it to filesystem and pass its path to setProxy.

Yup proxyconfig cant set per host but we can set a bypass list on the config https://code.google.com/p/chromium/codesearch#chromium/src/net/proxy/proxy_config.h&q=proxyconfig&sq=package:chromium&l=121

The PAC script can be set dynamically, users can always generate a PAC script on the fly and then save it to filesystem and pass its path to setProxy.

@deepak1556 I didn't know that, it is definitely a thing we can have.
