Once *one* byte of data has passed through a given filter within the filter chain, you cannot know if one filter is sitting on bytes of request or response body that it is waiting for completion. Maybe it has a partial token stored, maybe it's an incomplete multibyte sequence for a given code page translation. In both cases, once a byte is inside the filter chain, during a request (this is what I'm assuming your module does) you cannot add and drop filters. Those APIs are used for changing the filters before the request is processed.
