internal network proxy checking

internal network which is using pac url such as: http://proxypac.*.com/proxy.pac for proxying, might causing IDE(s) eg(Eclipse/Intellij) can't connect or install plugins, we can using the following code to generate the actual proxied url, and once get it then set it in IDE.

 

if you using dart sdk cmd mod, you can use 

写道

set https_proxy=username:%password%@proxy.*.com:8080

 

 

this tool code needs proxy-vole-20131209.jar
