If you are using eID you don't have to worry about TYPO3 caching at all.

If you use the approach of handling your ajax responder in a PAGE object
with a different typeNum (say 91), you can just disable caching in this
page object altogether. Something like that:

ajax = PAGE
ajax.typeNum = 91
ajax.no_cache = 1
ajax.10 < plugin.tx_yourplugin_pi
ajax.10.isAjax = 1

You just have a problem if you are handling your ajax response in the
same PAGE/pid/plugin environment as your regular script (which is either
an USER or an USER_INT. But I wouldn't recommend that anyway.
