If you work for a lot of different customers it becomes a drag to repeatedly change your proxy settings in your browser and trying to remember the different proxy servers and port configurations. While thinking about this problem I found a blog post from Jeff Wouters that addresses this problem.
In his blog he describes a great function to eliminate this problem, only it is based on PowerShell 2.0. PowerShell 3.0 has some new cmdlets that makes this task simpler.
Was once an enthusiastic PepperByte employee but is now working at Ivanti. His blogs are still valuable to us and we hope to you too.
