Before we delve too deeply into the administration of Railo Server, there is an important concept to get to grips with first. Even though, so far, we have been running only one website, Railo Server can actually run a number of websites.
A good example would be if we were running two different websites from our server, say our main website (http://localhost:8888) and another website, let's call it http://site2.local:8888.
Different websites might have different settings, and if you were an ISP, it probably would be maintained by different people. Railo Server allows you to do this by giving each context its own administrator and separating it from the other contexts, depending on which domain was used in the URL to access each site. These are called Web contexts.
Of course, the main administrator of the site should have access to all the settings and could also set "defaults" for the Web contexts. This is called the Server context.
You can visualize it as follows:
