The W3 Total Cache plugin changes the URL of various files in /w3-total-cache/lib/W3/Plugin/Cdn.php in the function *ob_callback*. It uses a series of callbacks to modify an output buffer. The code runs like this: w3_total_cache.php calls $root->run(); W3_Root::run calls $plugin->run() for each plugin in $this->_loaded_plugins W3_Plugin_TotalCache::run starts an output buffer which calls W3_Plugin_TotalCache::ob_callback W3_Plugin_TotalCache::ob_callback calls w3tc_do_ob_callbacks() … Read more
I was having this same issue and was able to correct it by expanding on Andy’s solution, however I only needed to force on value in particular to not use W3TC’s object cache.

You should use “Enhanced” if it’s available. It serves cached pages using the server’s URL rewriting capabilities, skipping PHP and WordPress entirely. It’s faster and more efficient.

This is the better option, as it means that all you need to do is increment the number in the query string and CloudFront will fetch this file automatically. Manually invalidate your … Read more
So, there are many sub-questions, i’ll try to address each. Views Counter Problem – I could make this Value/function be ran using Ajax. Once the new Cached/Static page is loaded, Javascript could then use Ajax to request and update the Views counter for that page. Totally agree: added benefit: loading it via ajax when “important” … Read more
Your solution with comment_author_proxyhash cookie will of course technically work – all caching plugins I know doesn’t analyze hash value and will just stop delivery of cached content based on comment_author_* cookie presense. Problem here is that page caching functionality is something websites really need and often page caching is configured exactly because naked WordPress … Read more
