I hacked iframe.php to pass url encoded variables to the iframe
Someone might find it useful. I did ;)
<div class="iframe-wrapper">
<?php
if($_GET != NULL) {
$encode_string = "?";
foreach($_GET as $key => $value)
{
$encode_string .= $key."=".$value."&";
}
}
?>
<iframe src="<?php echo $url.$encode_string; ?>" frameborder="0" style="height:<?=$height?>px;width:<?=$width?>px;">Please upgrade your browser</iframe>
</div>
