                          Predicates provide a simple way of making a true/false decision  based on an exchange. Many handlers have a requirement that they be applied conditionally, and predicates provide a general way to specify a condition. Predicates can be created programatically (they are just java classes that implement the Predicate interface), however there is also a simple language for specifying a predicate. Some examples below:
                          regex['/resources/*.\.css'] - regular expression match of the relative URL
                          regex[pattern='text/.*', value='%{i,Content-Type}, full-match=true] - Matches requests with a text/.* content type
                          equals[{'%{i,Content-Type}', 'text/xml'}] - Matches if the content type header is text/xml
                          contains[search='MSIE', value='%{i,User-Agent}'] and path-suffix['.js'] - User agent contains MSIE and request URL ends with .js
                          regex['/resources/(*.)\.css'] and equals[{'$1', 'myCssFile'}] - regex match, with a reference to match group 1 later in the expression
