[icap] if reqmod <> 204 - no respmod is sent by squid ?

Hello

i wrote a little perl icap server

when i issue a 204 response code on a reqmod, squid 3 make a respmod
when i issue a 200 response code on a reqmod, my squid 3 doesn't make a respmod

here is the result of the reqmod i am sending to squid 3

is this "normal" that squid3 doesn't make a reqmod after this ?
