ISL Light - Desktop v3 - Georeconnect for Single Address GRID (FEATURE) [ISLLIGHT-6596] More


Several changes were implemented to allow optimizing client connections in single address GRIDs where client DNS servers do not properly transfer client's IP address to ISL Conference Proxy (ICP):
"Check-Address: 1" header will be sent to ICP when doing geo reconnect to notify ICP that geo reconnect with server address in "Address-Reconnect" is supported
"Service-Reconnect: 1" header will be sent to ICP when doing service reconnect to notify ICP that service reconnect with geo reconnect is supported
"Address-Reconnect" response header will be handled as the new server address in the reconnect service reconnect and geo reconnect are now combined into the same event and executed at the same time:
- update service address in configuration, then
- reconnect to new server address
