[ciapug] special chars in urls

Fri Jun 24 09:20:56 CDT 2005

Hi,

There is another way to do it without any encoding at all using the
$PATH_INFO variable.

The URL would look something like this:

direct.php/http://www.foobar.com/blah.asp?id=5&action=poop

use $QUERY_STRING to access the query.

here is an example:

####### direct.php ######
<html>
<body>
<?
    echo("PATH_INFO = $PATH_INFO");
    echo("<br>");
    echo("QUERY_STRING = $QUERY_STRING");
?>
</body>
</html>
###########################

After running direct.php/http://www.foobar.com/blah.asp?id=5&action=poop
you would get:
PATH_INFO = /http://www.foobar.com/blah.asp
QUERY_STRING = id=5&action=poop 

Just remove the first '/' on $PATH_INFO and you are set to go.
