Hi,
As far as I know, it is not possible to configure a http proxy through which synchronization requests should be sent.
Or, due to the TCP port used by synchronization on the default server (TCP 9911), requests could be blocked by access lists on network devices.
So it would be nice to be able to put a line in the configuration file like:
HTTP_PROXY=http://myproxy.mycompagny.com:3128/
Regards.
Arnaud.
