Get records CRM API, when we use If-Modified-Since, does zoho cache the records for the whole request ?

Hi,

If we use If-Modified-Since in get records API, does zoho cache all the records page wise which are in the result ? If we modify any records belonging to the result of the api call with If-Modified-Since, does it affect the iteration ? , does  it change records in the next pages 1,2,3,4 ?
