nginx configuration which redirects based on the Host header. I use this in combination with a hosts file directing "myd" and "int" to localhost (or my workstation's IP if on a different computer) to allow cross-browser shortcuts to webapps not requiring a port. This means I can type "int/mypage" in Chrome, Firefox, IE, etc and be redirected to …

server {
  if ($host = 'int') {
		set $test I;
	}
	if ($host = 'myd') {
		set $test M;
	}

	if ($remote_addr = '127.0.0.1') {
		set $test '${test}L';
	}
	if ($remote_addr != '127.0.0.1') {
		set $test '${test}R';
	}

	if ($test = IL) {
		rewrite ^(.*)$ http://localhost:5050$1 break;
	}
	
	if ($test = IR) {
		rewrite ^(.*)$ http://10.0.40.150:5050$1 break;
	}
	
	if ($test = ML) {
		rewrite ^(.*)$ http://localhost:5051$1 break;
	}
	
	if ($test = MR) {
		rewrite ^(.*)$ http://10.0.40.150:5051$1 break;
