Does Falcon clear cache when forms are filled in?

The Falcon cache wouldn’t automatically clear when a form is submitted, but depending on how your site is made, that might not be an issue.

If users are logged in to your site (as WordPress users) when they submit forms, it should be ok already — Falcon only caches pages for users who are not logged in.

If you have certain pages that are always based on form input, and the page might look different for each visitor (based on their form submissions, even when they’re not logged in), then you can exclude those pages from the cache. Instructions for that feature are here:

If you have trouble setting these up, let us know if you need help.

I tried the basic 2 to 3 times improvement, and this is what happened to my site. When I switched it off it returned to normal. Any ideas…>

This usually means that your host has “gzip” compression turned on, while Wordfence’s caching also compresses your pages, or you may be using multiple caching plugins.

You might be able to disable compression in your site’s control panel, outside of WordPress, or your host might have to disable “gzip” for you. (They might also call it “deflate” or “mod_deflate”.)

If you do have any caching plugins, we recommend disabling them, since two plugins trying to cache at the same time will usually cause conflicts.
