Description:
------------
If you clic in the link to the same file, that only increments a count var in the session, you will see that it does twice.
i think that the problem is that "background" is written instead of "bgcolor".

Reproduce code:
---------------
file.php
--------
<table><tr><td background="#000000"> 
</td></tr></table>
<table><tr><td>require ($content);</td></tr></table>

content.php
-----------
<?php
if (!session_is_registered('countt')) {
session_register("countt");
$countt = 0;
}
else {
$countt++;
}
echo $countt;
?>
<a href="file.php?$content=content.php">click here to next count</a>



Expected result:
----------------
0 first time, next 1, 2, 3 ....

Actual result:
--------------
0 first time, next 2, 4, 6 ....
