title: MVC Style Filters on ASMX Web Services, is it possible?
body: <p>Is it possible to create MVC style filter attributes (like Authorize or HandleError) that work on ASMX Web Services?</p>
  
  <p>Specifically, I perform custom authentication on a number of my web methods and would like to wrap the code into an Attribute that throws an exception, if the authentication checks fail.</p>
