Installation

  1. Download and install the extension

    Recommended way is to use composer:

    composer require lochmueller/staticfilecache
    Copied!

  2. Change your .htaccess, vhost or nginx configuration

    Your TYPO3 installation needs to support rewriting to static files according to the templates in Configuration.

  3. Check access rights of the cache directory

    Make sure typo3temp/assets/tx_staticfilecache is accessible publicly

  4. Clear the TYPO3 cache

    After installation of the extension, you will need to clear the frontend cache and the backend cache. The reason for this is that the extension uses the TYPO3 cache hooks to generate static files. So if a page has already been cached by TYPO3, the hook will not be called and the static file will not be generated.

Verify the functionality

  • Check the statcifilecache configuration test in the backend module.
  • Enable basic.debugHeaders in the extension settings.
  • Open some frontend pages in a different browser than the one you're logged in with TYPO3.
  • Check the staticfilecache module - are there cached pages listed? good!
  • Check the your typo3temp/assets/tx_staticfilecache folder for content. Is there content? Good!
  • In your code, make sure there are no INT objects on pages you want to be cached. A single statically-uncacheable element will make the entire page statically-uncacheable.

  • In the second browser, hard reload the pages you previously called and check for x-sfc headers. Loaded? Good!

    x-sfc-state: TYPO3 - already in cache or x-sfc-state: TYPO3 - add to cache Great!

  • x-sfc-state: StaticFileCache - via Fallback Middleware That is ok, but there's something missing in the .htaccess.
  • x-sfc-state: StaticFileCache - via htaccess Perfect! You're set.

Third Party Extensions

helhum/typo3-secure-web

typo3-secure-web uses symlinks to move code out of the docroot. Therefore, it is important to make sure the statically cached pages are accessible for clients to reach. One way is to move the tx_staticfilecache into a path that is already covered by typo3-secure-web` redirects:

.htaccess:

# Full path for redirect
RewriteRule .* - [E=SFC_FULLPATH:typo3temp/assets/tx_staticfilecache/%{ENV:SFC_PROTOCOL}_%{ENV:SFC_HOST}_%{ENV:SFC_PORT}%{ENV:SFC_URI}/index]

# Do not allow direct call the cache entries
RewriteCond %{ENV:SFC_URI} ^/typo3temp/assets/tx_staticfilecache/.*
Copied!

LocalConfiguration.php:

'overrideCacheDirectory' => '../typo3-secure-web/typo3temp/assets/tx_staticfilecache/',
Copied!

in2code/powermail

Powermail form plugins are INT, so they disable static caching. Powermail has a global setting basic.enableCaching, that you can use, but that will disable php side prefilling functionality in all Powermail forms.
