node-http-cache is a dirt simple in-memory cache for http requests. it has an easy to use API that is exposed through CommonJS and JSON-RPC.

• super fast in-memory http request caching
• can be used as a CommonJS module in node.js
• can be used as a standalone server
• built in JSON-RPC API

let's suppose you have a web application that serves http requests, by using http-cache you can seamlessly cache the entire site in one line and drastically increase site performance without making ANY modifications to your existing code base. if you require more fine-tuned control, you can assign caching best on regex routes using http-cache's API (which can be used as a CommonJS module, or as a JSON-RPC web-service)

  curl http://npmjs.org/install.sh | sh

  npm install http-cache

  var http = require('http'),
      httpCache = require('http-cache');

  // this will start a new front-facing httpServer on port 8000
  httpCache.createServer(9000, 'localhost').listen(8000);

  // the target httpServer (which we will cache) is listening on port 9000
  http.createServer(function (req, res){
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.write('request successfully cached!' + '\n' + JSON.stringify(req.headers, true, 2));
    res.end();
  }).listen(9000);

See the demo for further examples.

if you have a suggestion for a feature currently not supported, feel free to open a support issue. node-http-cache is designed to just cache http requests
