session

The session object is a property of webContents which is a property of BrowserWindow. You can access it through an instance of BrowserWindow. For example:

var BrowserWindow = require('browser-window');

var win = new BrowserWindow({ width: 800, height: 600 });
win.loadUrl("http://github.com");

var session = win.webContents.session

Methods

The session object has the following methods:

session.cookies

The cookies gives you ability to query and modify cookies. For example:

var BrowserWindow = require('browser-window');

var win = new BrowserWindow({ width: 800, height: 600 });

win.loadUrl('https://github.com');

win.webContents.on('did-finish-load', function() {
  // Query all cookies.
  win.webContents.session.cookies.get({}, function(error, cookies) {
    if (error) throw error;
    console.log(cookies);
  });

  // Query all cookies associated with a specific url.
  win.webContents.session.cookies.get({ url : "http://www.github.com" },
      function(error, cookies) {
        if (error) throw error;
        console.log(cookies);
  });

  // Set a cookie with the given cookie data;
  // may overwrite equivalent cookies if they exist.
  win.webContents.session.cookies.set(
    { url : "http://www.github.com", name : "dummy_name", value : "dummy"},
    function(error, cookies) {
      if (error) throw error;
      console.log(cookies);
  });
});

proxy-uri-list = <proxy-uri>[","<proxy-uri-list>]
proxy-uri = [<proxy-scheme>"://"]<proxy-host>[":"<proxy-port>]

  For example:
       "http=foopy:80;ftp=foopy2"  -- use HTTP proxy "foopy:80" for http://
                                      URLs, and HTTP proxy "foopy2:80" for

       "foopy:80"                  -- use HTTP proxy "foopy:80" for all URLs.
       "foopy:80,bar,direct://"    -- use HTTP proxy "foopy:80" for all URLs,
                                      failing over to "bar" if "foopy:80" is
                                      unavailable, and after that using no

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