Caching in CS6 and CC

Question

Hello,
I am currently facing some problems with my plugins because of new caching features introduced in AE 6.0 and later.
The  result  of  plugins' work is sometimes dependent on previous processed frames, e.g. there are temporal dependencies. Thus, in order to correctly render, a plug-in should be applied to a consecutive series of frames. If the user goes randomly through the timeline, the temporal data is reset and temporal filtering is not applied.
It is also very imoprtant to maintain reproducibility of render results, that is, if  the user renders the same sequense multiple times, all the render results should be equal.
Reset  procedure  works fine in AE versions 5.0 and 5.5 and each frame is reprocessed correctly at the render step. However, in AE 6.0 and CC there is an improved caching mechanism that saves all the frames that the user looked at and, as I believe, it returns cashed results without calling the render (or any other) function in the plug-in. So, I can't guarantee that multiple renderings of the same sequence are equal, even if I use memory purging calls for each frame, because several frames at the beginning of a sequence may be cached, and a plug-in may get only some n-th frame as the first frame to render.
So, my questions are:
1. Are there any ways to overcome this problem inside the plug-in code?
2. Are there ways to purge AE cache JUST before the render starts, so that all the frames that need to be rerendered will be rerendered indeed?
Thanks!

I wouldn't rely on third party tools to solve font problems:

Tools like OnyX might ruin more than they repair.
Looks like your user account is corrupt. Illustrator might be a little more sensitive than other software in this regard
There are threads in Apple forums on how to transfer your stuff to a new user account.
