R – MS ISA Proxy connectivity

PROXY

Why are there so many programs that cannot work through an ISA proxy in Windows.

I can understand programs in OS's other than Windows and/or open sourced programs cannot connect through proxy. But I see many propitary Windows programs that can't.

Does it have to do with the libraries used in the project, or just plain laziness?

One of the main jobs of a ISA proxy server is to block communication.

So the idea is that systems that are on different sides of the proxy server should stop working, if you do not specifically open for the traffic between these systems.

For the Windows OS, I used Fiddler to work around the issue.

Install/Run Fiddler from www.fiddler2.com

Run gem:

$ gem install --http-proxy http://localhost:8888 $gem_name

Git – Getting Git to work with a proxy server – fails with “Request timed out”

Command to use:

git config --global http.proxy http://proxyuser:proxypwd@proxy.server.com:8080

change proxyuser to your proxy user
change proxypwd to your proxy password
change proxy.server.com to the URL of your proxy server
change 8080 to the proxy port configured on your proxy server

Note that this works for both http and https repos.

If you decide at any time to reset this proxy and work without proxy:

Command to use:

git config --global --unset http.proxy

Finally, to check the currently set proxy:

git config --global --get http.proxy
