Site Analyzer vs mod_pagespeed<\/h2>\n\n\n\n

I will\nexplain to you how to manage to validate ” the implementation of cache<\/strong> ”\nby the Site Analyzer<\/a> tool . Whether\nyou use mod_pagespeed<\/a> or\nnot on apache in version 2.X. It is not necessarily THE objective, but it\ntakes an important part in the scoring. And all the other tools will also\nask you to validate this parameter. (for the impatient, the solution is at\nthe very end of the article).<\/p>\n\n\n\n

Site Analyzer Paradox<\/h2>\n\n\n\n

Before\ncontinuing further on how to succeed, I want to warn you that doing this may\nslightly degrade your rating on Page Speed \u200b\u200bInsights<\/a> \u2026\nOn the home page I lost\n20 points<\/strong> on average on mobile and desktop. On the\ncontent pages I only have a loss of 5\/6 points.<\/p>\n\n\n\n

Cache-control the header so much sought<\/h2>\n\n\n\n

So, to\nfind out if you have cache on web resources (html, css, js, etc.) with apache\nnothing more simple. To do so, simply look at the headers returned by the\nwebsite’s web server. To see these headers under firefox you can use the firebug extension<\/a>  via the\n“Network” tab and by clicking on the desired resource: <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Cache-control<\/strong> , is the header that your server sends to tell the web\nbrowser to keep the file cached. So there are several values \u200b\u200bthat we\nwill look at right away.<\/p>\n\n\n\n
