.UNINDENT
.SH DESCRIPTION
.sp
Get the response header sent by the upstream server. This will only be useful in a callback on a
hook that is called after the upstream responds, and if there was an upstream response. For
instance, if the inbound request has no remap rule and \fI\%remap is required\fP then there will be no server response because no outbound
connection was made. In this case the function will return \fI\%TS_ERROR\fP\&.
.sp
The response header is returned in \fIbufp\fP and \fIoffset\fP\&. \fIbufp\fP is the heap in which
the header resides, and \fIoffset\fP is the location in that heap. These will be used in subsequent
calls to retrieve information from the header.
