Wccp web-cache

Does the "web-cache" command configure a local router content engine or does it still redirect web traffic to external content engines?

I'm confused between using the web-cache command or not when configuring wccp.

  • You mean 'ip wccp web-cache"?

    That enables you to TALK to a web cache device. Nothing is locally cached.

  • Then why would you need the command.

    Wouldn't this do the same?

    ip wccp 1

    int f0/0

    ip wccp 1 redirect in

     

    This is my confusion.

  • The service-identifier has nothing directly to do with what you are
    configuring.

    R1(config)#ip wccp ?
    <0-254> Dynamically defined service identifier number
    check Enable a WCCP check
    outbound-acl-check Enable acl check on original outbound interface
    version protocol version
    web-cache Standard web caching service

    R1(config)#ip wccp 1 ?
    accelerated Enable hardware acceleration
    group-address Set the multicast group
    group-list Set the access-list used to permit group membership
    mode Set the service mode
    password Authentication password (key)
    redirect-list Set the access-list used to permit redirection
    service-list Set the service-list used to set group properties


    R1(config)#

    So yes, you need the "ip wccp web-cache" to specifically talk about web
    caching. WCCP (especially version 2) can be much more.

  • Have the same issue here, I had tried to configured wccp without "ip wccp web-cache" and it seems working fine.

    One of the cache engine documentation support also shown "ip wccp web-cache" command doesn't needed when configure wccp.

    Pls CMIIW, Thanks.
