HELPER-MUX(8)	      User Contributed Perl Documentation	 HELPER-MUX(8)

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.
