[TYPO3-dev] Some TYPO3 questions

[Sancar Saran]

Hello there,

I'm trying to develop someting like ReaulURL extension and I need some inner 
TYPO3 knowladge.

My First question was.

1-) How can I execute my extesion on every request

2-) How can I forward requests to different page id from PHP. 
(like

 if($_REQUEST['id'] == 5) {
   $TYPO3_VAR['related_to_processed_page_id'] = 10;
 }
)


3-) Some times $GLOBALS['LANG']->lang was not available. Is there any reson 
for that. And is there any way to make sure  $GLOBALS['LANG']->lang available 
all times.

I hope I can translate my questions.

Regards

Sancar
