NAME
helper-mux - Concurrency protocol multiplexer for Squid helpers
SYNOPSIS
helper-mux helper-path [helper-options ...]
DESCRIPTION
helper-mux purpose is to relieve some of the burden squid has when
dealing with slow helpers. It does so by acting as a middleman between
squid and the actual helpers, talking to squid via the multiplexed
variant of the helper protocol and to the helpers via the non-
multiplexed variant.
Helpers are started on demand, and in theory the muxer can handle up to
1k helpers per instance. It is up to squid to decide how many helpers
to start.
The helper can be controlled using various signals: - SIGHUP: dump the
state of all helpers to STDERR
OPTIONS
helper-path
Path to the helper being multiplexed.
helper-options
Command line options for the helper being multiplexed.
KNOWN ISSUES
helper-mux knows nothing about the actual messages being passed around,
and as such cannot yet compensate for broken helpers.
It is not yet able to manage dying helpers.
