    This patch works :) Cisco Cache Engine is communicating correctly with 
    wccpd.
    
    Now I'm making production-testings. For now seems to be OK.

Great!  I'm glad to hear that!

    Few reflections:
    - location of scripts - I don't know where should it be, maybe in 
    /etc/wccp/scripts ?

Sigh... I don't specially like scripts under /etc (yeah, I know,
/etc/rc.d).  What does the FSSTD has to say about it?  IIRC, GNU tends
to use /usr/libexec for that.

    - dc called in scripts - ugly :)

Agreed.  Any way to convert a decimal number to hex or viceversa?  ip
rule, iptables and the like all differ slightly on what they expect. :-(

    - all caches should be called from some configuration file (maybe in 
    /etc/wccp/wccpd.conf.
    

Sorry, I don't understand this... Do you want a config file to list the
valid caches?

    
    For now it looks OK. It's "raw" but works fine.
    

Ok; I'll see to it.  I'm working now on WCCP v2.
