title: RESTful PUT and DELETE and firewalls
body: <p>In the classic "RESTful Web Services" book (O'Reilly, ISBN 978-0-596-52926-0) it says on page 251 "Some firewalls block HTTP PUT and DELETE but not POST."</p>
  
  <p>Is this still true?</p>
  
  <p>If it's true I have to allow overloaded POST to substitute for DELETE.</p>
