nodejs http请求压缩（没有表达，但是可以用玉渲染文件）

Question

客户端请求时如何发送压缩的压缩文件？

例如，我有：

var zlib = require("zlib"),
    http = require("http");

http.createServer(function(req, res) {
    /*req.url is the url of the file requested
    how to compress and send the file here?
    consider that usually (facoltative) I can renderize the file also with Jade.renderFile()
    so the best solution is to compress the output before sending to client */
}).listen(80);

以及如何缓存以避免多个gzip请求？
