headers and cookies

I was wondering if i need to do anything to enable headers and cookies on my php 4.2 installation on apache 1.3.* running on xp.

When I tried the following:

<?php
header('//localhost/project/admin/error1.htm');
?>

I get an Internal Server error telling me that the server encountered an internal error or misconfiguration, i have checked the error logs to find:

[Mon Aug 12 02:41:41 2002] [error] [client **...] malformed header from script. Bad header=//localhost/project/admin/erro: c:/php4/php.exe

i have checked the phpinfo () config and it says that my cookies are set

session.use_cookies (local and master value = on).

and there is no mention about headers in the configuration i think.

So can someone tell me where im going wrong.

Many Thanks

Did you try setting a valid header? The one you are setting is nonsense, and the server is right to complain.

tried it with www.php.net and surprisingly it worked.

The reason i used that header is because i want that file to load and since im working locally, i used the localhost file path.

do i need to add anything else to make it work??
