To maintain the example short some security good practices have been omitted, but be very careful about
malformed URIs. For example, depending on how you handle them, a URI might contain the sequence
%00 which will prevent further appending of an extension, or ../ that will navigate potentially
through the filesystem and outside the public visible web repository. A good way to prevent malicious
intentions is to match the URI correctness using regular expressions that are described in detail in
Chapter 8 .
