sockets - socketio4net-problems with proxy -

i have been asked take on project previous developer had used socketio4net,

hence learnt of socketio4 project now.

the problem employer facing clients having proxy servers.

we have installed our product(client side) on clinics uses socketio4net , websocket. connect our main azure server sending data. in clinics without proxy,we not facing issues. proxy server, our service not starting.

if have implement ssl process, big overhead

how achieve ssl , proxy settings sockets in general? socketio4net provide other options?

do have change http classes webclient?

in experience proxies , school's in particular, vast majority turned out firewall based issue. port using, 80, 443 or else? if issue, clinics need either whitelist server ip, or allow ip:port combo you've set.

for quick test @ clinics have issues - try these 2 sites (probably others sites can find too):

http://websocketstest.com/ - tests ports 80, 8080, 443 , without ssl - or work? (this site great end-user @ site run you, can results link - double bonus points!)

http://www.websocket.org/echo.html

are both of sites above able connect?

hope helps...
