title: WCF vs ASHX for file transfer
body: <p>I need my web server to make a call through the firewall to an internal server and retrieve a binary file.  On the internal server, which is better to use: a WCF service or an ASHX file to take the request and return the bytes of the file?</p>
  
  <p>If a WCF service, are there any tutorials you can direct me to as I have not done much with WCF?</p>
