Currently, your ICAP server sends an embedded HTTP request _and_ an embedded HTTP response (header) which may violate the ICAP specs and is definitely not supported by Squid (because it does not make sense in Squid context -- only one message can be adapted at a time). Please note that the ICAP RESPMOD _request_ does (usually) contain both an embedded HTTP request and an embedded HTTP response, but since the ICAP server cannot modify the embedded request (too late for that!), the ICAP server should only return an embedded response (the same or a different/adapted one).
