How to run sv_*_header.txt samples #56

Closed samnemo94 closed 4 years ago

What is the configuration to run SocketQueue with, so that it accepts the samples with headers?

Hi!

SocketQueue uses headers for upstream connection only. It does not read headers sent by clients. By default the length header is present.

Below is the example of self test mode where a binary client sends an echo packet that is being passed to an upstream with the length header. The response also comes with the header. The header data is marked with bold.

$ node socketQueue.js --upstreamHost=localhost --upstreamPort=5000 --listenPort=2014 --listenHttpPort=8080 --vv --echoServerPort=5000 --testClients=1 --testTargetHost=127.0.0.1 --testTargetPort=2014 2020-04-07 22:49:08 - info: Important: starting...
