Scripts and Extensions
These are applications which can be preprocessed before becoming html. For example, a c pretty printer is included which will perform syntax highlighting on software. Another example is PHP, a "pre" html processor. Before each file is served its extension is checked against this table and the appropriate preprocessor is run. Notice that in our example we use php preprocessing for html. This is handy if you want to add preprocessing to existing files but you do not want to break existing link structures in search engines.
