title: How to temporarily disable git http proxy
body: <p>I am using git behind a corporate firewall, and I am successfully cloning external projects by using the http.proxy --global config.</p>
  
  <p>My problem arises when I want to clone through http on the intranet. I suspect that the proxy config interferes with the intranet request.</p>
  
  <p>I know I could reset the config before using the intranet, but that is not very user friendly.</p>
  
  <p>I also saw this <a href="https://stackoverflow.com/a/16612442/28275">answer</a>, but it seems to apply only to an existing repository.</p>
  
  <p>Is there a way to deactivate the proxy usage only for one command invocation? In this case, the initial clone?</p>
