Caching for my site

726mediallc

Is there an alternative to using WP plugins to speed up caching of my site https://bestelectricwaterboilers.com?

Caching is not something that can be "sped up". It either happens or it
does not.

For wordpress sites you can of course write your own plugins or code to
send HTTP caching  headers and respond to. It is far easier and often
better to use something already existing though, if you can find a
plugin that works well.

Use the redbot.org tool to test your site behaviour with any options you
choose. Right now it is reporting that your site is already caching but
not producing correct Vary headers.

Thank you for the quick reply, but what are "Vary headers?"

"Vary" is an HTTP header presented by servers for use by caches. It
tells the cache which parts of a client request message to use when
looking for possible cache entries.

Without it only the URL is used and that prevents HTTP features like
compressed responses, per-user customization of page contents, login vs
non-login views of pages, and user language translations from working
properly.

Technical details at <https://tools.ietf.org/html/rfc7231#section-7.1.4>


PS. since you seem not to already know HTTP the wordpress plugins might
be the best way to start from. See what they do to HTTP messages vs the
HTTP documentation (RFCs 7230 to 7235), with the redbot tool as a way to
get a quick explanation about caching related features they enable.
