Wincache Support on Plesk Shared Hosting
Our Plesk shared hosting accounts support Wincache for PHP apps. This feature can increase the performance of PHP applications through caching on your hosting account.
Microsoft has a document that outlines how Wincache works here. Our Plesk shared hosting accounts can support everything outlined in the article. However, by default, we enable everything outlined in the What Wincache Does for "Free" section.
