[squid-users] HEAD requests: pass through?

If my understanding is correct when the client already has the content it
sends a HEAD request to the squid and it will be checked whether the content
on the squid is newer than the local cache of the client.

Is it possible to configure the squid in a way that such requests are not
answered by the squid itself but passed through to the internet? Because it
may happen that the content on the internet has changed - in this case the
client would compare against the older content from the suqid cache (this
should be avoided).

The scenario should be: 

1. If the client does not have the content ask the squid and
  1a)  If it has the content take this. 
  1b) If it does not have the content get it from the internet. 

2. If the client already has the content and just sends a HEAD request pass
this to the internet in order to check against the newest version.
