| Summary | 0001816: proxy.pac file is reachable even if http proxy is not active | ||||||||
| Description | The proxy auto configuration file (proxy.pac) is downloadable always even if the http proxy is not working. This may provide an erroneous proxy configuration to a browser which has the auto detection function active. This issue may prevent clients to correctly access to internet. The file should be available only when the proxy is active. | ||||||||

The problem happens on blue with hotspot activated as well. This may lead configuration problems or connection slowdown. It happens always before and after login. |

Can you please try to download the proxy.pac file when the proxy is disabled? In that case the proxy.pac file should configure the browser automatically in order to go directly! I think that's the correct way, rather than making the file inaccessible. |

i agree with peter. if proxy.pac orders to go directly it is the right behaviour. |
|
(0002485) luca-endian (developer) 2009-06-08 15:06 |
ok.. my fault I've re-checked you are right, the file is always downloadable but tells to go direct and that's right :) I believed to the customer that told that he had problems, I didn't control the content of the file. |

I changed my mind. I've discovered a pc which has problem with proxy autoconfiguration in our office. efw: Mercury without proxy http Pc: Windows XP Internet explorer 7 with proxy auto: works fine Firefox 3 with proxy auto: doesn't work Firefox 3 without proxy auto: works fine I renamed the proxy.pac to make it unreachable then Firefox 3 with proxy auto: started working This discover let me think that users, who complained about this problem, are right, and probably somewhere there is a problem. I don't know if there is a typo in the proxy.pac, but probably in order to avoid any possible mistake I would go for proxy.pac unreachable with proxy disabled. You never know, maybe in certain condition the proxy.pac is wrong. That's just my suggestion.. Here is the proxy.pac content: function FindProxyForURL(url, host) { if (isPlainHostName(host) || shExpMatch( url, "*192.168.58.15*" ) ) return "DIRECT"; else if (host == "127.0.0.1") return "DIRECT"; else if (isInNet(host, "192.168.58.0", "255.255.255.0")) return "DIRECT"; else return "PROXY 192.168.58.15:8080; DIRECT;"; } |

for a disabled proxy, this proxy.pac output is wrong! it must be *always* DIRECT. that should work with every browser, otherwise the browser is not proxy.pac capable and should not even try to download that file. |
|
(0002708) luca-endian (developer) 2009-06-30 13:40 |
Mhh the above output is what I have.. At first sight I don't see any line in the proxy.pac script for the PROXY=off case but maybe I'm wrong. |
|
(0002710) mike-f (updater) 2009-06-30 14:00 |
using return "PROXY 192.168.58.15:8080; DIRECT;"; the clients first tries to connect using the proxy (which is turned off) if that fails he goes direct shouldn't it just be this? function FindProxyForURL(url, host) { return "DIRECT"; } |
|
(0002711) luca-endian (developer) 2009-06-30 14:13 |
I agree, something at the beginning like: if PROXY=off then go DIRECT exit So we are sure that nothing can spoil that file.. just a suggestion |
|
(0002715) mike-f (updater) 2009-06-30 15:09 |
in the case of "proxy=off" the proxy.pac should only contain return "DIRECT"; the if-clause (PROXY=off) is not needed (and will consume client-time for searching & calculating as it will not find the proxy) |
|
(0002717) mike-f (updater) 2009-06-30 15:16 |
ack - file should exist in case somebody is pushing rules over Group Policies ("use the following proxy for IE") admins won't have any issues in Windows-Domains when proxy.pac is not existing |
|
(0002718) luca-endian (developer) 2009-06-30 15:18 |
The if clause was intended to be placed on the perl script which returns the proxy.pac |
|
(0002719) mike-f (updater) 2009-06-30 15:21 |
tnx for the hint ;-) |

it is DIRECT now when proxy is disabled |
