Access Google App Engine Development Server Remotely

By default Google AppEngine's (GAE) development webserver doesn't accept remote requests. If you'd like to make your devel GAE application available remotely you can use a simple proxy to forward requests. I chose to use pen proxy because it is sooooo simple. To install pen on ubuntu do

sudo apt-get install pen

to do it on OSX with macports do

sudo port install pen

Once it is installed startup your GAE application. Then start up pen like this:

pen 8079 localhost:8080

Now pen will forward requests from port 8079 to your app running at 8080.
