### When to use node-http-proxy

|
||||
<pre>
|
||||
var options = {
|
||||
router: {
|
||||
'foo.com': '127.0.0.1:8001',
|
||||
'bar.com': '127.0.0.1:8002'
|
||||
'foo.com/baz': '127.0.0.1:8001',
|
||||
'foo.com/buz': '127.0.0.1:8002',
|
||||
'bar.com/buz': '127.0.0.1:8003'
|
||||
}
|
||||
};
|
||||
</pre>
|
||||
|
||||
The above route table will take incoming requests to 'foo.com' and forward them to '127.0.0.1:8001'. Likewise it will take incoming requests to 'bar.com' and forward them to '127.0.0.1:8002'. The routes themselves are later converted to regular expressions to enable more complex matching functionality. We can create a proxy server with these options by using the following code:
|
||||
The above route table will take incoming requests to 'foo.com/baz' and forward them to '127.0.0.1:8001'. Likewise it will take incoming requests to 'foo.com/buz' and forward them to '127.0.0.1:8002'. The routes themselves are later converted to regular expressions to enable more complex matching functionality. We can create a proxy server with these options by using the following code:
|
||||
<pre>
|
||||
var proxyServer = httpProxy.createServer(options);
|
||||
proxyServer.listen(80);
|
||||
</pre>
|
||||
|
||||
### Proxy requests using a 'Hostname Only' ProxyTable
|
||||
As mentioned in the previous section, all routes passes to the ProxyTable are by default converted to regular expressions that are evaluated at proxy-time. This is good for complex URL rewriting of proxy requests, but less efficient when one simply wants to do pure hostname routing based on the HTTP 'Host' header. If you are only concerned with hostname routing, you change the lookup used by the internal ProxyTable:
|
||||
|
||||
<pre>
|
||||
var options = {
|
||||
hostnameOnly, true,
|
||||
router: {
|
||||
'foo.com': '127.0.0.1:8001',
|
||||
'bar.com': '127.0.0.1:8002'
|
||||
}
|
||||
}
|
||||
</pre>
|
||||
|
||||
Notice here that I have not included paths on the individual domains because this is not possible when using only the HTTP 'Host' header. Care to learn more? See [RFC2616: HTTP/1.1, Section 14.23, "Host"][1].
|
||||
|
||||
### Proxy requests with an additional forward proxy
|
||||
Sometimes in addition to a reverse proxy, you may want your front-facing server to forward traffic to another location. For example, if you wanted to load test your staging environment. This is possible when using node-http-proxy using similar JSON-based configuration to a proxy table:
