WinAIM (AIM service) use this snac to keep connection alive. This is usefull
|
|
when it use proxy server to connect to BOS. Proxy servers can disconnect client
|
|
if there is no activity for some time. ICQ use channel 5 FLAPs for this issue.
|
|
<br><br>
|
|
It is strongly advised for client developers to use channel 5 FLAPs to keep
|
|
connection alive because this save traffic. SNAC(01,16) is deprecated and not
|
|
used anymore.
