I have some questions. Please help me!!! Suppose we downloading a big file (some Mb) through ISA server with our web filter installed. If web filter processes event SEND_RAW_DATA for a long time (a few seconds, for example) what would happen? Would it pause receiving file from internet? Data that coming at this time (while processing event) will be lost or it would be accumulated? How can I pause receiving file from Internet (using filter)? Can handler of SEND_RAW_DATA be called while handling previous SEND_RAW_DATA for the same request? Sorry for bad English.
