Hello everyone;

I'm playing with Oxwall core code for a while in order to customize it for my own project. There is something in code that makes me confused.
As you know, we can enable "maintenance" mode in OW_Application->handleRequest() function which is executed after the code that reads $_SERVER['REQUEST_URI'] in OW_Request->getRequestUri(). But $_SERVER['REQUEST_URI'] is set to maintenance uri!!! This is just like a magic.

How this is possible?
Where $_SERVER['REQUEST_URI'] is set?
Is this related to "output buffering" (ob_) capabilities enabled in Oxwall?

Thanks beforehand. :-)
