VHOST-Proxy

[Axel Kittenberger]

Hi list, yet another question (I know its getting much in the last days :-).

Suppose I want to host a second legacy website with Apache-PhP on my
VPS otherwise running awesome node.js (not my blog, its yet something
else). So I check request.headers.host and if its the VHOST for the
legacy website, I want to proxy that request to say localhost port
8080 running the Apache.

Any code snippets to properly and compactly proxy GET as well POST requests?

I've seen node-http-proxy, but its Documentation only explains howto
set up a standalone (reverse)proxy rather than integrate it to an
existing node.js server occupying the port 80.

var httpProxy = require('http-proxy')
;

httpProxy.createServer(options, function(req, res, proxy) {
if(req.headers.host === 'whatever.example.com') {
proxy.proxyRequest(req, res,
{ host: 'localhost'
, port: '8080'
}
)
return
}
res.writeHead(400, {})
res.write('Bad Request: Missing "Host"')
res.end()
})

Thank you.

The thing that confuses me is, why httpProxy.createServer(...);

Cant I just create http.createServer() handle requests normally for
the main node site, and in my request handler create a proxyRequst
only when it relates the VHOST?

Yes. https://github.com/nodejitsu/node-http-proxy/tree/master/examples

No. All of the examples proxy through httpProxy.createServer

[Oliver Leics]

var http = require('http')
, httpProxy = require('http-proxy')
, proxy = new httpProxy.RoutingProxy()
;

http.createServer(function(req, res) {

if(req.headers.host === 'whatever.example.com') {
proxy.proxyRequest(req, res,
{ host: 'localhost'
, port: '8080'
}
)
return
}

res.writeHead(400)
res.end('Bad Request: Unknown "Host"')
}).listen(80)

Awesome, thanks!

BTW: httpProxy.createServer(...) can proxy websocket-requests. And it
supports ssl connections.

There are several entry points into the proxying API
