content engine 590

[ciscoforum]

trying to connect a content engine 590 to a cisco router which will have web-cache enabled.

The diagram is like this: pc (lan)- fa0/0router-isp. the engine is on the same lan of fa0/0.

One question bother me is the keyword "in" and "out" from ip wccp web-cache redirected in /out. Noticed new version supports the "in"option. Little confusion about the "in" and "out". Does "out" mean : if the pc send http via fa0/0 to router, since the keyword "out" the router will redirect the http out to the fa0/0 to engine? then keyword "in" is useless. Or the other way,"in" means allow incoming traffic from fa0/0 to be redirected? Confused.

Hope to get a good explanation here. Thanks very much.

in and out tells the router where to intercept the HTTP request from the client.

So, you can intercept on inbound - incoming interface - interface where traffic enters the router. This is the "IN" keyword.

You can also intercept it on outbound - outgoing interface - interface where traffic is normally forwarded by the router. This is the "OUT" keyword.

In your case you want the 'in' on interface fa0/0.

One reason to go for 'in' is much better performance than out.

[but you could do out on the serial interface going to your isp]

If the cache is on the same interface as the clients, you need the command 'ip route-cache same-interface' on interface fa0/0 to permit traffic to be redirected to the cache correctly.
