headers and variables

I can't find any mention of this and I can't figure out why this isn't working.

I can send this just fine:
header("Location: test.php");

but this does not work:
$loc = "test.php";
header("Location: $loc");

I checked, and the var is getting parsed. Why wouldn't this work?

no idea, but put it all in the var

$loc = "Location: $page";
header($loc);

???

That forces a "save as" dialogue box. 🙁 Good thought though.

I've had a weird problem like this before too. Omit the space between the colon and your variable.
