I was searching for a solution to redirect an url to another one to be more productive, or switch webapp tools easily without thinking about it.
First, I tried editing hosts file (windows only solution), but the thing is you can only redirect to an IP. It’s not so convenient!
I suggest you to try, instead of editing the hosts file in windows, to use a plugin like Redirector for Firefox or Redirector for Chrome.
It’s working great to keep me from browsing some websites when I don’t want, in exemple for productivity purposes, or to force myself to use a new service. One could imagine using a redirector to stop using hotmail.com and use any another custom service, without changing any other habits.
