WebPerf Cloudflare This forum's pagespeed.conf

Dedicated thread to keep a tally and history of this forum's pagespeed.conf changes and settings for Nginx PageSpeed module. Update mod_pagespeed and ngx_pagespeed documentation is now listed together at Installing From Packages

current /usr/local/nginx/conf/pagespeed.conf configuration used on this very forum as follows:

Note:

If you're using https/SSL need additional settings which are not found in my forum's posted pagespeed.conf PageSpeed HTTPS Support - PageSpeed Module — Google Developers

---

For example if I had https/SSL enabled on the forums I need to add to pagespeed.conf this line. Changing your paths appropriately for your domain of course.

Code:

pagespeed LoadFromFile "https://community.centminmod.com" "/home/nginx/domains/community.centminmod.com/public";
# https://www.modpagespeed.com/doc/configuration#preserve-url-relativity
pagespeed PreserveUrlRelativity on;

looks like indeed pagespeed might need these settings PageSpeed HTTPS Support

For CentOS

Code (Text):

  # https://www.modpagespeed.com/doc/https_support
   pagespeed SslCertDirectory /etc/pki/tls/certs;
   pagespeed SslCertFile /etc/pki/tls/cert.pem;

Update: Feb 23, 2016

Looks like a centmin mod user's question on ngx_pagespeed issue tracker at CSS, JS not combing & Images are not rewriting · Issue #1129 · pagespeed/ngx_pagespeed · GitHub has led to learning something new for me too

instead of using LoadFromFile format like this which may incorrect try to optimise non-static files PageSpeed Authorizing and Mapping Domains

Code (Text):

pagespeed LoadFromFile "http://centminmod.com" "/home/nginx/domains/centminmod.com/public";
pagespeed LoadFromFile "https://centminmod.com" "/home/nginx/domains/centminmod.com/public";

you can use format from LoadFromFileMatch and LoadFromFileRuleMatch to tell ngx_pagespeed to only optimise static files with specific extensions !

Code (Text):

pagespeed LoadFromFileMatch "^https?://centminmod.com/" "/home/nginx/domains/centminmod.com/public/";
pagespeed LoadFromFileRuleMatch disallow .*;
pagespeed LoadFromFileRuleMatch allow \.css$;
pagespeed LoadFromFileRuleMatch allow \.jpe?g$;
pagespeed LoadFromFileRuleMatch allow \.png$;
pagespeed LoadFromFileRuleMatch allow \.gif$;
pagespeed LoadFromFileRuleMatch allow \.js$;

The first line matches both http and https version of site so only use if you have SSL certificate and https and http both working. If only have http site and NO https use

Code (Text):

pagespeed LoadFromFileMatch "^http://centminmod.com/" "/home/nginx/domains/centminmod.com/public/";
pagespeed LoadFromFileRuleMatch disallow .*;
pagespeed LoadFromFileRuleMatch allow \.css$;
pagespeed LoadFromFileRuleMatch allow \.jpe?g$;
pagespeed LoadFromFileRuleMatch allow \.png$;
pagespeed LoadFromFileRuleMatch allow \.gif$;
pagespeed LoadFromFileRuleMatch allow \.js$;

or just old LoadFromFile

Code (Text):

pagespeed LoadFromFile "http://centminmod.com" "/home/nginx/domains/centminmod.com/public";
pagespeed LoadFromFileRuleMatch disallow .*;
pagespeed LoadFromFileRuleMatch allow \.css$;
pagespeed LoadFromFileRuleMatch allow \.jpe?g$;
pagespeed LoadFromFileRuleMatch allow \.png$;
pagespeed LoadFromFileRuleMatch allow \.gif$;
pagespeed LoadFromFileRuleMatch allow \.js$;

 

The Disallow directives are to work around some Nginx Pagespeed incompatible Xenforo elements such as json requests like

Code:

pagespeed Disallow */js/dark/postrating.js*;
pagespeed Disallow */js/xenforo/tabalerts.js*;
pagespeed Disallow */lost-password/lost;
pagespeed Disallow */lost-password/*;

pagespeed Disallow */posts/*/report*;
pagespeed Disallow */proxy.php*;

 

Thanks @RoldanLT

 

Cleaned up and revised my pagespeed.conf to the one above.

 

To prevent pagespeed from deferring them as they can break stuff that requires them early on depending on the style etc.

 

could be style specific ?

 

yeah should be, although would defeat a huge purpose of using pagespeed for other js files if pagespeed didn't enable defer js filter (with Disallow exclusions where necessary)

 

Maybe for folks with advertising conflicts starting a new thread with troubleshooting steps http://community.centminmod.com/threads/nginx-pagespeed-troubleshooting-steps.32/ might help

 

Started a thread for this http://community.centminmod.com/threads/ngx_pagespeed-advertising-conflicts.186/

 

Added a few more Xenforo specific pagespeed filter exclusions, when editing a post, the editor lags when loading due to pagespeed deferring js files. So disabling these allow the editor to render immediately rather than deferred

Code:

pagespeed Disallow */edit-inline*;
pagespeed Disallow */save-inline*;
pagespeed Disallow */posts/*/save-inline*;
pagespeed Disallow */posts/*/edit*;
pagespeed Disallow */posts/*/delete*;
pagespeed Disallow */posts/*/ip*;
pagespeed Disallow */posts/*/report*;

 

it is now

 

no it isn't required to use FetchHttps https://developers.google.com/speed/pagespeed/module/https_support#https_fetch and to me it would slow the requests compared to LoadFromFile https://developers.google.com/speed/pagespeed/module/https_support#load_from_file local request method
