Please select from one of the above choices:

[2]>

Enter a number corresponding to the web proxy cache settings you require:

Safe 

The least caching and the most adherence to RFC #2616 
compared to the other modes.

Optimized Moderate 

caching and moderate adherence to RFC #2616. 

Compared to safe mode, in optimized mode the Web Proxy 
caches objects when no caching time is specified when a 
Last-Modified header is present. The Web Proxy caches 
negative responses.

Aggressive

The most caching and the least adherence to RFC #2616. 
Compared to optimized mode, aggressive mode caches au-
thenticated content, ETag mismatches, and content without 
a Last-Modified header. The Web Proxy ignores the 
no-cache parameter.

Customized mode

Configure each parameter individually.
