Proxy

When you go on the web and look at a site, that site can often find out information about you. Using a proxy is a way of avoiding that happnening.

To understand how this happens, let's look at a simplified way of how the web works with out a proxy ...

  1. You type another.org into your browser.
  2. Your computer says to the internet "please can you send this page to me. This is where I am."
  3. The webpage comes back to you.

This means that, in step 3, the website you are asking for knows who you are.

Here's how connecting through a proxy works ...

  1. You type another.org into your browser.
  2. Your computer says to the to your proxy "please can you send this page to me. This is where I am."
  3. The proxy says to the internet "please can you send this page to me. This is where I am." It does not pass the details of you computer on to the server that hosts the webpage you have asked for.
  4. The webpage comes back to the proxy.
  5. The proxy forwards the webpage to your computer.

This means that the server of the page you are viewing only has information about the proxy. It has no information about your computer.
