Hi,
Data Trickling is used to keep the connection between client and ICAP client busy. Between ICAP client and ICAP server there is no data trickling. Once the file was submitted the ICAP client needs to wait until the ICAP server is ready.
Usually ICAP clients expect a response within a specific period of time before they report a timeout. This limit needs to be extended as MWG sometimes takes a lot of time to scan complex archives.
