I have read that to avoid caching in Node.js, it is necessary to use:
res.header(\'Cache-Control\', \'no-cache, private
After spelunking through source code for the express and fresh modules, this works from the server side (before res.end is called):
req.headers['if-modified-since'] = undefined; req.headers['if-none-match'] = undefined;
Nasty, but it works.
