It is perfectly legal to send a query string on a POST request.

A quite likely casuse (if you upgraded from Squid 1.X) is if the CGI
program is broken and expects a extra CRLF after POST requests. See
RFC2068 (end of section 4.1) for a suitable note on this issue...

If your problem is this CRLF issue then setting
persistent_client_posts off
in Squid 2.1 may help you work around this problem.

It is. POST is defined as using a URL, and query string is part of the
URL syntax without restriction to specific methods.

CGI is also well defined for POST requests with a query string, and such
requests is used by many CGI programs to avoid having a hidden
parameters in the forms.
