How to proxy web apps using nginx?

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

Solution: sum(1)(2)(3)(10)() = 16

Solution: sum(1)(2)(3)(10)() = 16

  1. Solution 1: Cache the value in the function itself. But, It will not work when the function is called multiple times at the same time.
function sumAggr(num) {
  if (sumAggr.sum === undefined) {
 sumAggr.sum = 0;

How to execute the .bashrc file with command running through SSH login?

I wanted to use command

ssh myhost.com 'some_command' and some_command exists in /var/some_location so I tried to append /var/some_location in $PATH environment by editing $HOME/.bashrc

but that wasn't working. because default .bashrc(Ubuntu 10.4 LTS) prevent from sourcing by code like below:

# If not running interactively, don't do anything
