Welcome back!

I thought you had gone missing permanently.

You mean these comments from the code?

 If anyone wanted to define a custom service, we would want the
following options

   wccp2_service number priority [flags] [ports]

[flags] should include:

   hash_source_ip - to use the source ip address to determine which
cache to send the packet to (can be used to make sure the same ip always
hits the same cache). This would override the default beahviour of using
the destination ip.

   defined_ports_source - to use the source port to determine whether a
packet will be redirected by WCCP (useful for catching reply packets if
the proxy server is forging the source ip address)

   proto_udp - to override the default protocol type of tcp

Anything else you remember being hardcoded for which it may make sense
to add a config option?

Done. But does not yet build proper due to some bugs/WCCP dependencies..
will fix those shortly.
