vary
Manipulate the HTTP Vary header
Installation
This is a Node.js module available through the
npm registry. Installation is done using the
npm install command:
$ npm install vary
API
var vary = require('vary')
vary(res, field)
Adds the given header field to the Vary response header of res.
This can be a string of a single field, a string of a valid Vary
header, or an array of multiple fields.
This will append the header if not already listed, otherwise leaves it listed in the current location.
// Append "Origin" to the Vary header of the response
vary(res, 'Origin')
vary.append(header, field)
Adds the given header field to the Vary response header string header.
This can be a string of a single field, a string of a valid Vary header,
or an array of multiple fields.
This will append the header if not already listed, otherwise leaves it listed in the current location. The new header string is returned.
// Get header string appending "Origin" to "Accept, User-Agent"
vary.append('Accept, User-Agent', 'Origin')
Examples
Updating the Vary header when content is based on it
var http = require('http')
var vary = require('vary')
http.createServer(function onRequest (req, res) {
// about to user-agent sniff
vary(res, 'User-Agent')
var ua = req.headers['user-agent'] || ''
var isMobile = /mobi|android|touch|mini/i.test(ua)
// serve site, depending on isMobile
res.setHeader('Content-Type', 'text/html')
res.end('You are (probably) ' + (isMobile ? '' : 'not ') + 'a mobile user')
})
