+DOC_START
+ 206 (Partial Content) responses is an ICAP extension that allows the
+ ICAP agents to optionally combine adapted and original HTTP message
+ content. The decision to combine is postponed until the end of the
+ ICAP response. Squid supports Partial Content extension by default.
+
+ Activation of the Partial Content extension is negotiated with each
+ ICAP service during OPTIONS exchange. Most ICAP servers should handle
+ negotation correctly even if they do not support the extension, but
+ some might fail. To disable Partial Content support for all ICAP
+ services and to avoid any negotiation, set this option to "off".
