title: Pre-compress static files in IIS 6
body: <p>I am implementing Gzip compression for CSS and JS files on my site and just need to double check something.</p>
  
  <p>Is the file compressed on every request? or is it collected and sent from the Temporary folder (if the file exists)? I just want to be sure that my files are not compressed on every request.</p>
  
  <p>Also, is this a default behaviour or do I need some extra configurtion?</p>
  
  <p>And last,  do I need to worry or configure something when using hash tags in the path (to inform the browser that the file has changed) and static file compression? or it should work with no problem.</p>
  
  <p>Edit: I am just using static compression</p>
  
  <p>Many thanks</p>
