PHPMonkey?
I have been experimenting with the built in server to see if I could get it to act as a proxy
running on localhost. What I wanted to do was manipulate pages before they were sent to my browser,
like Fiddler and other programs can. I got it to work for http traffic but not https. I see errors
in the console, when the built in server gets an https request, saying that the request is
malformed. Anyway, if you want to alter http traffic just before it hits your browser, then you can
extend the class in this router to override the external_resource_handler method. Right now all it
will do is transparently proxy pages but you can do whatever you want between getting the page and
showing the page. @see: DOMDocument in the manual http://php.net/manual/en/class.domdocument.php
