Hi,
Just recently came across very strange problem - posting a comment on a cached page as an anonymous user, disables caching for whole cached site for current anonoymous user - as far as I can tell, current anonymous user behaves like logged in user - newly visited pages are not cached at all by this anonymou user.
To reproduce:
I used fresh install + created few nodes
Turned caching on (1day both settings)
Manually visited all nodes. (cache_page got filled with links)
Cleared browser cache.
Posted a comment to one node.
Since last point, current anonymous user is able to visit only non cached pages. Visiting non cached pages do not add them into cache_page table, which is similar to logged in user.
Clearing browser cache fixes it and current anonmous user visits cached pages again.
What can cause this issue, or is it default behavior?
Thank you for answer.
