Resolved "Only Nginx" with gzip + zlib compression? Pro/Contra

[Dukemaster]

Thank you, very much for great support. I get it here by your amazing tutorial and changing the input syntax a little, I didn't write the items in a special way: How to compile NGINX with additional modules ( pagespeed / cache_purge / headers-more / and others )
. What I now discovered, without any setting with BROTLI together with Pagespeed. The test-time by Qualys (ssllabs.com) is 69 seconds, yesterday and all last weeks OVER (!!!) 2 minutes with long cipherlist. So this is the co-influence right from using Pagespeed+Brotli.

brotli_types text/html

Hi @UFHH01
I followed your instruction but get the warning "duplicate entryMIME type text/html": (But in the last box is my gzip.conf yesterday deleted to avoid double configurations from /etc/nginx/conf.d. I used it the last 9 months for Apache+Nginx as reverse proxy and since around one week for ONLY Nginx configurations. There you left text/html.
Shall I ignore the warning or leave text/html out and risk less brotli functionality.
I found no hints on internet to this special part of brotli settings.

root@server:~# nginx -t

Hi Dukemaster,

... and again, pls. note the difference between WARNINGS/NOTICES and ERRORS, pls.!


Yes, you might get warnings as described, because with my suggestion, you use "brotli" AND "gzip" compressions for the MIME type "text/html".

If you don't like the idea, if the WARNING disturbs you in whatever way, or if you think, that you would like to use only "brotli" OR "gzip" compression for this MIME type, pls. feel free to leave out this option at the "brotli" - modifications OR the "gzip" - modifications. Simple... isn't it? ^^

Hi @UFHH01 ,
no such things disturbing me in no way. Only the possibility to have less compression or risking troubles by ignoring the warning are interesting for me.
I already read that pagespeed configuration mistakes could end in less functionality and even harm the whole webserver configuration. This is no place for playing like somewhere else on webserver
