I have used ProcMon.exe
to see what happens to my application when there is no internet. My application is an electron
application that makes use of websocket to connect to backend service resides in other computer.
FYI, the example of websocket address is ws://10.5.14.72:8080/Model
.
AFAIK, HTTP request from websocket will go through proxy server if there is one exist(please correct me I am wrong).
FYI, when there is no internet, the application reacts very slowly as it keeps reconnecting to some unknown address as shown in ProcMon.exe
which i believe were proxies but i can't find in internet options
. Below is the details:
TCP Reconnect x.x.x.x:50074 -> 203.208.39.198:https SUCCESS
TCP Reconnect x.x.x.x:50075 -> 203.208.39.198:https SUCCESS
TCP Reconnect x.x.x.x:50077 -> 203.208.39.199:https SUCCESS
TCP Reconnect x.x.x.x:50078 -> 203.208.39.199:https SUCCESS
TCP Reconnect x.x.x.x:50077 -> 203.208.39.199:https SUCCESS
TCP Reconnect x.x.x.x:50078 -> 203.208.39.199:https SUCCESS
TCP Reconnect x.x.x.x:50080 -> 203.208.39.193:https SUCCESS
TCP Reconnect x.x.x.x:50081 -> 203.208.39.193:https SUCCESS
TCP Reconnect x.x.x.x:50080 -> 203.208.39.193:https SUCCESS
TCP Reconnect x.x.x.x:50081 -> 203.208.39.193:https SUCCESS
These connecting attempts happen for few minutes before it finally reaches the target address.
So, can I know whether these 203.208.39.xxx:https
addresses represent proxies?
