Server Variables are variables that IIS sets and provides to your application and are relative to the HTTP request and response. They are an accumlation of information based on HTTP headers, IP connections, authentication, authorization, etc.

An example of using a rewrite rule with Server Variables could be to provide the original URL of your resource prior to the the URL rewrite. Your target application could then use the original URL in some piece of logic such as tracking uses of the original URL.

HTMLEncode will take special characters that are part of the HTML markup syntax and encode them to be output as HTML. This makes it easier to send output from the server side in that you don't have to manually create the markup as you're sending it.
