Fragmented Caching with AJAX

Dear Mr. Hoffmann & ZMS-Devellopers,

according to your last reply:

A)
I tried, but I did not find AJAX requests for post-loading content. What
did I wrong ;-) ?
Is this intended as a ZMS internal feature or has the template to
support this?
If it has to be the template, which of the ZMS default templates does
support this feature?

B)
Does this feature take care of non-AJAX or non-javascript able browsers
as many of the textonly browsers are which are often used by visually
impaired people?

C) 
Does this feature distinguish between anonymous requests, where a page
can generally be cached in most cases and authentified requests, where
most often the menu is personalised but the content can get cached?
