httpbin.org provides a useful server to test HTTP/2 protocol, there are several cases which can be used to test HTTP clients. You can find below a list of main tests provided: HTTP Methods: Testing different HTTP verbsAuth: Auth methodsStatus Codes: Generates responses with given status codeRequest inspection: Inspect the request dat...
In a previous post, I show a comparison between HTTP2 and HTTP1 performance using a single connection (see HTTP2 vs HTTP1 performance). In this post I will show a comparative between HTTP2 and HTTP1 introducing a latency and showing how latency can affect to HTTP protocol requests. When a client do a request, there is a latency, more or less depend...
RFC 7540 and RFC 7541 contains the full specification of HTTP/2 protocol and in the process of implementing a new HTTP/2 client for sgcWebSockets library, is important to use external tools to check if client component is working as expected. One of this online tools is hosted in: https://http2.golang.org/ This web offers some tests for HTTP/2 clie...
sgcWebSockets supports a wide range of protocols, HTTP/2 is the protocol which is in development right now. HTTP 1.1 has been the most used HTTP Protocol and wide implemented in server and clients during the last 15 years. But as internet grows, applications and webs growed and the amount of loaded data increased, the shor...

Once the connection has been established, if no peer sends any data, then no packets are sent over the net. TCP is an idle protocol, so it assumes that the connection is active. Disconnection reasons Application closes: when a process is finished, usually sends a FIN packet which acknowledges the other peer that connection has been closed. But if a...
