Applying Inspection and Connection Limits to HTTP Traffic to Specific Servers
In this example (see Figure 21-3), any HTTP connection destined for Server A (TCP traffic on port 80)
that enters the security appliance through the outside interface is classified for HTTP inspection and
maximum connection limits. Connections initiated from server A to Host A does not match the access
list in the class map, so it is not affected.
Any HTTP connection destined for Server B that enters the security appliance through the inside
interface is classified for HTTP inspection. Connections initiated from server B to Host B does not match
the access list in the class map, so it is not affected.
