 * Is there a way to clear a specific cached post or page when someone posts a comment?
 * My blog is not very active so I set the cache expiration to 5 days, but I want
   that the cache for a post to be refreshed when someone comments, which is also
   rare.

 * Solve it, hehe. Just added this code to my theme’s functions.php file.
 *     ```
       add_filter("comment_post_redirect", "ws_plugin__qcache_clear_on_post_page_comment", 10, 2);
       function ws_plugin__qcache_clear_on_post_page_comment($location, $comment) {
       	ws_plugin__qcache_clear_on_post_page_creations_deletions($comment->comment_post_ID);
       	return $location;
       }
       ```
   
 * then edited wp-content/plugins/quick-cache/includes/functions/clearing-routines.
   inc.php, edited the ws_plugin__qcache_clear_on_post_page_creations_deletions 
   function:
 * Changed line 34 to (Quick Cache v2.2.7):
 * `if (in_array ($pagenow, ($pages = array ("edit.php", "post.php", "post-new.php","
   wp-comments-post.php"))))`
 * *added ‘wp-comments-post.php’ in the whitelist
    This will clear the cache for
   this specific post. and, depending on settings, will clear the cache for the 
   home page also.

 * The function to clear the cache was changed in the recent version of the plugin.
   And I haven’t found a solution yet for it.
