/*
Session data is ommitted purposefully, mostly because it's not likely that the data
that resides in $_SESSION at this point is the same as the data that the application
started off with (for most apps, it's likely that session data is manipulated on most
pageloads).
The goal of storing get, post and cookie is to help explain why an application chose
a particular code execution path, pehaps it was a poorly filled out form, or a cookie that
overwrote some default parameters. So having them helps. Most applications don't push data
back into those super globals, so we're safe(ish) storing them now.
We can't just clone the session data in header.php to be sneaky either, starting the session
is an application decision, and we don't want to go starting sessions where none are needed
(not good performance wise). We could be extra sneaky and do something like:
if(isset($_COOKIE['phpsessid']))
{
session_start();
$_xhprof['session_data'] = $_SESSION;
}
but starting session support really feels like an application level decision, not one that
a supposedly unobtrusive profiler makes for you.
