Autoproxy behind a corporate firewall that uses a website to configure proxy
in [TCL]

From: jalitt on 25 Jun 2008 23:19 Hello, I am a tcl user behind a corporate firewall. I'd like to develop an app that communicates with a server outside of the firewall, and I'd like to write this app in tcl. The only problem is that autoproxy does not work because my company stores proxy info on a website. IE knows the url and uses it just fine, but autoproxy seems unable to do so. Is there anyway to grab the proxy info from that site and configure the http package accordingly? Sincerely, Joshua Litt

If you are in the same case as I am, you're out of luck :-) Indeed all the logic is written in Javascript to be executed by the client (the browser)... In my case the workaround is to identify the proxy to use for the "outside" which is (in my company) constant for a given location of the client machine (my company is multi-site). Yes, it's awfully inelegant, but taming a SpiderMonkey just for that was contrary to my religion ;-) -Alex

From: jalitt on 26 Jun 2008 14:49 Thanks for all the prompt replys. Pat, I'm curious as to how libcurl might be used to solve this problem? I'd hate to have all that nasty code for dealing with windows objects embedded forever in my tcl code. I'm not against making the user enter a url if autoproxy cannot discover proxy information from system standard places. Glenn, my corporate firewall returns a similar .pac file with a similar FindProxyForURL function. How can this function be called from tcl? Sincerely, Joshua Litt

Pat, would you be so kind as to answer my question on libcurl ? -Alex |
