Hi Jose,
Thanks for your questions.
Please ensure that you have read through all the documentation which is provided with the plugin, as it may help explain some of these points. In your WordPress admin area, go go the plugins page, click on “Configuration & Status” next to FlexiCache, and then select “Documentation” from the drop-down list at the stop.
1) Remember that FlexiCache does not cache items when you are logged in as an administrator, so if it doesn’t *feel* like it’s going faster, try visiting the site in a browser which is not logged in. Google Chrome, for example, has an incognito mode which is useful for this.
2) The ENABLE_CACHE constant is nothing to do with FlexiCache and will not have any effect on the plugin’s behaviour.
3) I am not clear what you mean by “It is neccesary standard mode or I can use default httaccess?”, but the documentation which comes with the plugin explains information about the .htaccess file. See also point 4 below which can be implemented using .htaccess
4) The site speed report you have posted shows good results for HTML pages, but poor results for CSS, JavaScript, images etc. Your web server serves these directly – they do not go via FlexiCache – so you need to configure your web server to set expiry times for these. These page have information which might help with those issues:
– https://stackoverflow.com/questions/6878427/leverage-browser-caching-how-on-apache-or-htaccess
– https://httpd.apache.org/docs/2.2/mod/mod_expires.html
5) To see whether FlexiCache is working, look at the response HTTP headers. FlexiCache adds one called “X-FlexiCache” which indicates the cached status of the page. You can also enable HTML comments in the config options, but these will only be added when service uncompressed responses.
6) Yes, FlexiCache supports gzip, deflate, and uncompressed responses. This is explained thoroughly in the documentation and configurable in the plugin options – there is section called “Compression”.
Hope that helps,
Si.
