Request number handling in squid 1.2

Hello,

We are looking at altering squid to work with an ICP
concentrator/redirector/'smart neighbour' that we have built.

I am looking through the squid 1.2b23 code in the icpv2.c file and see
that squid 1.2 may do something differnet to the request number based on
the type of request it is. The ICPV2 draft says :

   Request Number
      An opaque identifier. When responding to a query, this value must
      be copied into the reply message.

But the code that has us scratching our heads is :

 method = header.reqnum >> 24;
    /* Squid-1.1 doesn't use the "method bits" for METHOD_GET */
    if (METHOD_NONE == method || METHOD_ENUM_END <= method)
        method = METHOD_GET;

is this the case, can anybody tell me if the request number is modified
(by altering the high or low bits) by squid other than to increment it on
a per ICP basis.
