/**
* Autoptimize's magic 404 handler.
*
* Configure your webserver to have requests for files that are no longer in
* /wp-content/cache/autoptimize/ to redirect to this file. AO's .htaccess file
* will have a "Errordocument:" directive to automatically do this.
*
* This file has simple logic to redirect to the "fallback" files that are
* created automatically by AO to avoid visitors seeing broken pages or
* Googlebot getting utterly confused.
*
* Error logging is off by default (don't want to flood your php errorlog, but
* can be enabled by this code snippet:
*
* add_filter( 'autoptimize_filter_cache_fallback_log_errors', '__return_true' );
*
* Warning: the fallback files might not apply to all pages, so this is a just
* a temporary solution, you really should clear any page cache to avoid requests
* to files that don't exist in AO's cache.
