var BufferRes = require('express-buffer-response');
app.use(function(req, res, next) {
if (req.method != "GET") return next();
// here be cache read logic
BufferRes(res, function(err, bl) {
// get the err from onFinished
// and a bufferList containing the actual response chunks
// here be cache store logic
bl.pipe(fs.createWriteStream('cachefile'));
});
next();
});Works with express-session since 1.0.3
