CERT VU#435052 - intercepting proxy vulnerability

See:
   http://www.kb.cert.org/vuls/id/435052

 From an HTTP perspective, there are a number of potential reactions;

1) intercepting proxies are bad; we told you so!

2) we should accommodate intercepting proxies in HTTPbis, because  
they're a reality.

2a) we should note this type of attack in Security Considerations, and  
more strongly recommend that clients send an absolute URI on the  
request-line, even when not using a configured proxy.

Just food for thought...

Cheers,
