title: How do I call a local shell script from a web server?
body: <p>I am running Ubuntu 11 and I would like to setup a simple webserver that responds to an http request by calling a local script with the GET or POST parameters. This script (already written) does some stuff and creates a file.  This file should be made available at a URL, and the webserver should then make an http request to another server telling it to download the created file.  </p>
  
  <p>How would I go about setting this up?  I'm not a total beginner with linux, but I wouldn't say I know it well either.  </p>
  
  <p>What webserver should I use?  How do I give permission for the script to access local resources to create the file in question?  I'm not too concerned with security or anything, this is for a personal experiment (I have control over all the computers involved).  I've used apache before, but I've never set it up.</p>
  
  <p>Any help would be appreciated..</p>
