Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

#The Shadow DOM Diaries

Feature design is hard, and takes time. With time, it doesn't matter how public and consistent you are with communication during design process. In the end, it all will look like a jumbled mess of emails and bug comments. That seems bad. To make things less bad, I decided to start writing these little docs. Here they are. I may add more. Or not. Whatevs.

Sometimes You Need to Build a Larger Thing First looks back at the road we've traveled.

Shadow DOM Evolution outlines the path forward.

Why Do We Only Allow Children in Insertion Points provides a glimpse into the reasoning behind current insertion point design.

You will need a VPS/Unix Shell account on a remote machine sitting in a country with some sane laws.
from your local machine, do:

$ ssh -D 1080 user@host

On your browser (or other applications), go to the network connection settings, select the option to use a proxy and leave everything blank except the SOCKS option, where you fill in hostname as localhost or 127.0.0.1 and port number as 1080 (or whatever you filled in above). That is all!

Outgrowing the Cloud (Mike Moore)

Requests hitting the same load balancer can't handle HTTP and HTTPS at the same time because of SSL issues
If you are trying to access an outside resource behind a firewall, you have to tell them every time you get a new webserver so they can whitelist the new IP
If you know the IPs of your web servers and database servers, you can have requests hit these directly and bypass the load balancers.
Could buy your own data center, but then you have to buy a load balancing router. Those are fucking expensive (tens or hundreds of thousands of dollars)
