Hi Rainer! Thanks you again. This is what I tried: FilterDeclare COMPRESS FilterProvider COMPRESS DEFLATE "%{CONTENT_TYPE} =~ m#text/html#" FilterProvider COMPRESS DEFLATE "%{CONTENT_TYPE} =~ m#text\/html.*$#" FilterProvider COMPRESS DEFLATE "%{CONTENT_TYPE} =~ m#text\/html\.*$#" FilterChain COMPRESS gzip_compression FilterProtocol COMPRESS DEFLATE change=yes;byteranges=no And still the same. I.e. chunked content :( Is my syntax incorrect and doesn't cover [Content-Type is 'text/html;charset=UTF-8'] header? -----Original Message----- From: Rainer Canavan [mailto:rainer.canavan+httpdusers@xxxxxxxxxx] Sent: 04 August 2020 13:39 PM To: users@xxxxxxxxxxxxxxxx Subject: Re: Apache mod_autoindex and mod_deflate (gzip). Can't get pages compressed [...] > FilterProvider COMPRESS DEFLATE "%{Content_Type} = 'text\/html.*$'" I don't think you can use regular expressions with just '=', you'll have to use '=~' search 'regex' in the documentation at https://httpd.apache.org/docs/2.4/expr.html for the exact syntax required. rainer --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
