#flags and options are:
#
# enabled: default true, set true/false to enable/disable plugin for specific host
#
# remove-accept-encoding: this sets if the plugin should hide the accept encoding from origin servers
# - to ease the load on the origins
# - for when the proxy parses responses, and the resulting compression/decompression
#   is wasteful
#
# cache: when true, caches the compressed response; when false, caches only the uncompressed
#   response and compresses on-the-fly from cache. Vary: Accept-Encoding handles alternates.
#
# compressible-content-type: wildcard pattern for matching compressible content types
#
# allow: wildcard pattern for allow/disallowing compression on urls
# - prefix pattern with ! to disallow
#
# compressible-status-code: a comma separated list of status codes in which to enable compression
#
# minimum-content-length: minimum content length for compression to be enabled (in bytes)
# - this setting only applies if the origin response has a Content-Length header
#
# gzip-compression-level: compression level for gzip (1-9, default 6)
# - 1 is fastest compression (lowest compression ratio)
# - 9 is slowest compression (highest compression ratio)
#
# brotli-compression-level: compression level for brotli (0-11, default 6)
# - 0 is fastest compression (lowest compression ratio)
# - 11 is slowest compression (highest compression ratio)
#
# brotli-lgwin: window size for brotli compression (10-24, default 16)
# - larger values provide better compression but use more memory
# - 10: 1KB window, 16: 64KB window, 24: 16MB window
#
# zstd-compression-level: compression level for zstandard (1-22, default 12)
# - 1 is fastest compression (lowest compression ratio)
# - 22 is slowest compression (highest compression ratio)
