This is picky, I know, but on line 79, "... ended with a abort!" isn't correct English. It would be more correct to say "... ended with an abort!"

The rule is, if the noun following a/an (indefinite article) starts with a vowel sound, then use "an" otherwise use "a".

You wouldn't say "... an ball" or "... an chair" (Chrome is even complaining to me know for trying to write it wrong).
You would say "... a ball" or "... a chair". Likewise, you wouldn't say "... a apple" or "... a AJAX call". You would say "... an apple" or "... an AJAX call". 😃
Reference

This is required:
public boolean function onApplicationStart(){
return true;
}

and this allows the desired page to render:
public void function onRequest(String targetPage){
include arguments.targetPage;
}

seems only needed for onRequest... I never use that so is good to know, rather than need to have.
