[Bug 1222912] Re: Error parsing proxy.pac

[Michael Greene]

I'm having a very similar issue here.

If I tell Firefox to use a proxy file (i.e. set
network.proxy.autoconfig_url = file:///etc/proxy.pac and
network.proxy.type = 2), and that pacfile exists, everything works fine,
even if returning two proxies.

If I then rename or remove that proxy.pac, firefox goes along on its way
merrily, but the IcedTea plugin fails. Running firefox from the cli
yields the following output:

java version "1.7.0_79"
OpenJDK Runtime Environment (IcedTea 2.5.6) (7u79-2.5.6-0ubuntu1.12.04.1)

Unable to use Firefox's proxy settings. Using "DIRECT" as proxy type.

Title:
  Error parsing proxy.pac

Status in icedtea-web package in Ubuntu:
  New

Bug description:
  Ubuntu 12.04.3 LTS 32-bit up-to-date

  When using the following proxy.pac, IcedTea doesn't open embedded java
  applets in Firefox or Chromium:

  function FindProxyForURL(url, host) {
     return "PROXY 192.168.1.3:8080; DIRECT";
  }

  I had to change to:

  function FindProxyForURL(url, host) {
     return "PROXY 192.168.1.3:8080";
  }

  There is some problem passing & parsing proxy.pac configurations.

  I tried using proxy.pac using system proxy configuration, browser
  proxy configuration and IcedTea Web Control Panel.

  My conclusion is that proxy.pac only work if they return one proxy
  possibility (as my above example).
