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.
