Collection Cache Settings
b2evolution version 4.1
The Caching fieldset is part of the Blog Properties since b2evo version 3.x.
These settings control Caching and Cache Levels (see section High level caches) for the current Blog.
Starting in version 4.1, it is only possible to enable page caching when using AJAX forms at the same time. This prevents issues with cached Crumbs (nonces). (Crumbs are a security 6 antispam feature that requires serving a different random "crumb" string to each individual user. We cannot cache a single string and serve it to multiple users. That would defeat the purpose.)
In addition, AJAX Forms also prevent comment and message forms from being indexed and cached by search engines like Google. This makes it harder for spam bots to find and post to these pages. (Note: If they still post spam, the comments go to the moderation queue anyways).
