Script Dumpster: Setting Proxy server settings

Contents

OK, so I’m at my new job and for the first time in years, I have to deal with proxy servers again…

Since I’m used to having full admin rights on my machine and unrestricted internet, this was somewhat of a shock, while perfect for my productivity as well 😛

Unfortunately for them, I have since been informed that a special IT proxy is available, which provides this access, hence me being able to update my site again 🙂

Here’s a quick script which allows me to switch from “normal” proxy (while pre-defined you can set it to whatever you prefer) to IT proxy or disable it all together
