Good Day Sirs.
i have an issue while using node js to just proxy a GET request
through node JS and it hangs giving the following issue
Error 4
{ [Error: socket hang up] code: 'ECONNRESET' }
i have tried different methods but still the same
all that the code does is just remove the range request forcing
youtube videoplayback to fall back to the old request i;e; getting
full file not 1.7M ranges from it with a hope that squid-cahe would
cache it
much regards for the help in advance
hereby is the code i am using
#!/usr/bin/node
