If you need to exclude specific pages from being cached while using W3 Total Cache you simply add/register the pages.

- goto Performance > Page Cache
- scroll to Advanced > Never cache the following pages
You then add the entries as so:
/page-name/
/another-page-name/

It also supports regular expressions:
That’s all you really need to do to skip caching and exclude individual pages from cache if you’re using W3 Total Cache.
