title: When should I be responding to HTTP HEAD requests on my website
body: <p>My google app engine website is getting errors on the main url for HEAD requests because I am not accepting them.  According to <a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html#sec9.4" rel="nofollow noreferrer">this</a>, the HEAD request is for <a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html#sec9.4" rel="nofollow noreferrer">"testing hypertext links for validity, accessibility, and recent modification"</a></p>
  
  <p>What should be my "normal" response to HEAD requests be?</p>
  
  <p>I started accepting HEAD requests, to stop the errors from showing in my logs, but only on the main url.</p>
  
  <p>Can someone point me in the right direction?</p>
