NAME

6       helper-mux - Concurrency protocol multiplexer for Squid helpers
7

SYNOPSIS

9       helper-mux helper-path [helper-options ...]
10

DESCRIPTION

12       helper-mux purpose is to relieve some of the burden squid has when
13       dealing with slow helpers. It does so by acting as a middleman between
14       squid and the actual helpers, talking to squid via the multiplexed
15       variant of the helper protocol and to the helpers via the non-
16       multiplexed variant.
17
18       Helpers are started on demand, and in theory the muxer can handle up to
19       1k helpers per instance. It is up to squid to decide how many helpers
20       to start.
21
22       The helper can be controlled using various signals: - SIGHUP: dump the
23       state of all helpers to STDERR
24

KNOWN ISSUES

33       helper-mux knows nothing about the actual messages being passed around,
34       and as such cannot yet compensate for broken helpers.
35
36       It is not yet able to manage dying helpers.
