Redirect from HTTP to HTTPS using meta redirects
|
||||
|
||||
## Installation and Usage
|
||||
|
||||
```bash
|
||||
npm install --save redirect-https
|
||||
```
|
||||
|
||||
```js
|
||||
'use strict';
|
||||
|
||||
var express = require('express');
|
||||
var app = express();
|
||||
|
||||
app.use('/', require('redirect-https')({
|
||||
body: '<!-- Hello Mr Developer! Please use HTTPS instead -->'
|
||||
}));
|
||||
|
||||
module.exports = app;
|
||||
```
|
||||
|
||||
## Options
|
||||
|
||||
```
|
||||
{ port: 443 // defaults to 443
|
||||
, body: '' // defaults to an html comment to use https
|
||||
, trustProxy: true // useful if you haven't set this option in express
|
||||
}
|
||||
```
|
||||
|
||||
* This module will call `next()` if the connection is already tls / https.
|
||||
* If `trustProxy` is true, and `X-Forward-Proto` is https, `next()` will be called.
|
||||
* If you use `{{URL}}` in the body text it will be replaced with the url
|
||||
|
||||
## Demo
|
||||
|
||||
```javascript
|
||||
'use strict';
|
||||
|
||||
var http = require('http');
|
||||
var server = http.createServer();
|
||||
var securePort = 8443;
|
||||
var insecurePort = process.argv[2] || 8080;
|
||||
|
||||
server.on('request', require('redirect-https')({
|
||||
port: 443
|
||||
port: securePort
|
||||
, body: '<!-- Hello! Please use HTTPS instead -->'
|
||||
, trustProxy: true // default is false
|
||||
}));
|
||||
|
||||
server.listen(insecurePort, function () {
|
||||
console.log('Listening on http://localhost.daplie.com:' + server.address().port);
|
||||
});
|
||||
```

# Why meta redirects?

# Other strategies

|
||||
If your application is properly separated between static assets and api, then it would probably be more beneficial to return a 200 OK with an error message inside

|

# Security
|
||||
|
||||
The incoming URL is already URI encoded by the browser but, just in case, I run an html escape on it
|
||||
so that no malicious links of this sort will yield unexpected behavior:
|
||||
|
||||
* `http://localhost.daplie.com:8080/"><script>alert('hi')</script>`
|
||||
* `http://localhost.daplie.com:8080/';URL=http://example.com`
|
||||
* `http://localhost.daplie.com:8080/;URL=http://example.com`
