[squid-users] problems with few squids cutting off initial http://domainame

hello, i have following problem :
squid 1 < squid 2 < squid 3,
when i ask squid 3 for a http://www.google.com/search?q=something
it returns :
/search?q=something is invalid URL..

when i contact with squid 2 or squid 3 all works fine... what could be cause
of this?

squid 2 have squid 1 as cache peer with round-robin and no-query directive,
squd 3 have squid 2 as parent.
