Chapter 23 WAN Optimization, Web Cache, Explicit Proxy, and WCCP : Web caching and SSL offloading : Example: Web caching of HTTP and HTTPS Internet content for users on an internal network : General configuration steps
  
General configuration steps
This section breaks down the configuration for this example into smaller procedures. For best results, follow the procedures in the order given:
1. Add HTTP web caching to the security policy that all users on the private network use to connect to the Internet.
2. Add HTTPS web caching.
3. Add a protocol options profile to look for HTTP traffic on ports 80 and 8080 and HTTPS traffic on ports 443 and 8443 and add this protocol options profile to the security policy.
If you perform any additional actions between procedures, your configuration may have different results.
