Caching does not seem to work properly on safari?

Hi I have searched the docs and discussions and haven't found mention of this. My newly setup cache enabled wordpress site does not properly deal with comment postings on Safari web browsers (mobile or desktop), but DOES deal with them properly on FF and Chrome.

- If a known or unknown user posts a comment using a FF or Chrome browser, comments work as expected
- if a known or unknown user posts a comment using Safari (desktop or mobile) their comment will not show up for them, it seems to disappear. The page does not have its cache cleared for safari users the same way it does for others, and they will only be able to see their comment (which did in fact post to the backend at least) once there has been a full purge cache initiated from the wordpress admin.
