nodejs_http_servers

A NodeJS sample to show how a server makes a HTTP request to another server

Usage

To run a sample of how this works:

Run npm install
Run both servers by typing these on the command line: node index.js (port 3000) and node otherServer.js (port 3001)
On the server with port 3000, you can make a HTTP request by typing this URL on the browser

http://localhost:3000/route/userId/123/name/guesswho

On the same server with port 3000, you can also call this endpoint. The other server (having port 3001)--after receiving the request--will do a redirect to itself with a new endpoint before sending back the response to the calling server. Moreover, the HTTP connection for this will be persistent (with keep-alive and connection pooling).

http://localhost:3000/redirectRoute/userId/123/name/guesswho

If you look at the console, you will see that the request is routed to the other server--which in turn also sends a response back to the calling server (that initially made the request)
As an alternative, you can also install wrk and make multiple requests to the server. This command line tool is useful for a more detailed benchmarking when making requests.

wrk -t1 -c1 -d1s http://localhost:3000/redirectRoute/userId/123/name/guesswho

The servers uses Express and Request NodeJS modules
