/**
|
|
* 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.
