mod_pagespeed and php selector

[oceanwave]

I've installed mod_pagespeed from easyapache4. I followed these instructions https://support.cpanel.net/hc/en-us/...ividual-domain to enable mod_pagespeed for specific accounts only.

I'm using cloudlinux php selector to set php version.

mod_pagespeed is working for html such as index.html, css, and js files served by apache.

However, mod_pagespeed is not working for php pages served by cloudlinux php_selector such as index.php

Is there a way to get mod_pagespeed to work with php pages with php_selector secure php version?

We tried reproducing the issue on our lab servers and seems the issue is not related to PHP packages, and is not related to the CageFS enabled/disabled. We were not able to make the individual mod_pagespeed working for any domain if it is disabled globally even with native PHP. Can you please confirm it's working with PHP when enabled globally? Do you use mod_lsapi as PHP engine?

Thanks very much for taking a look.

Yes, mod_pagespeed is working with PHP when enabled globally.

I'm running php as fcgi, php selector with php 7.3/7.4, and cagefs enabled.

With /etc/apache2/conf.modules.d/510_pagespeed.conf set to ModPagespeed on, multiple individual css and js files called from index.php are combined into an optimized css / optimized js file and the html lines in the index.php output then have a call to the mod_pagespeed-combined css and combined js file; mod_pagespeed is altering the html of the php file to optimize and optimizing the called js/css components.The X-modpagespeed header appears when viewing the php file in chrome developer tools -> network -> headers

(sub-note: ModPageSpeedEnableFilters rewrite_css, ModPageSpeedEnableFilters rewrite_javascript, ModPageSpeedEnableFilters combine_css, ModPageSpeedEnableFilters combine_javascript work when enabled in .htaccess for a single site for php files with mod_pagespeed enabled globally, but ModPageSpeedEnableFilters remove_comments and ModPageSpeedEnableFilters collapse_whitespace only work for php files when enabled in global 510_pagespeed.conf; these latter two work for html files when enabled in .htaccess.)

With ModPagespeed off in the /etc/apache2/conf.modules.d/510_pagespeed.conf and ModPagespeed on in /home/site/www/.htaccess, the html source of index.php is not altered to combine multiple css / js files.

(sub-note: testing was inconsistent in the following regard: the html within a php file was never optimized with mod_pagespeed disabled globally and enabled with .htaccess, and multiple css/js files were not combined, but in some tests the js and css files called by the index.php file were optimized rewritten by mod_pagespeed; In other tests it was necessary to add text/css and text/javascript to the AddOutputFilterByType MOD_PAGESPEED_OUTPUT_FILTER text/html in 510_pagespeed.conf and it required several reloads; I'm not clear why it optimized the called js and css files in some tests without those added and in other tests not until text/javascript and text/css were added; with it enabled globally it optimizes and combines the called files without having to add the additional types to the OUTPUT_FILTER line.)

mod_pagespeed is interesting as it gives the mobile lighthouse score a noticeable improvement on some sites where scripts are complicated and have lots of individual css/js calls/comments, etc.,

But it would be great if it were possible to enable it on a per-account basis as I don't want to risk introducing glitches to all accounts unless the site could benefit in a noticeable way. (and much easier to enable on an account-by-account basis to give time to spot any possible glitches it could introduce)

I'm also not sure if mod_pagespeed would introduce security concerns the way it caches all sites in a cache directory outside of cagefs... (?)
