Why 500 error appears when I use HEADER()?

[Anon]

I used the header() function to process user authorization.My code just like this:
<?php
Header("WWW-Authenticate: Basic realm=\"Member\"");
Header("HTTP/1.0 401 Unauthorized");
?>

But when I exec it, system shows the 500 error:internal server error.And the Apache error log shows:[Tue Aug 10 01:23:55 1999] [error] [client 127.0.0.1] malformed header from script. Bad header=HTTP/1.0 401 Unauthorized: c:/php4/php.exe.

Could someone please tell me the reason and how I can deal with it?

Thanks

Quan

are you using the php as apache module or as cgi ? because this is only available for the apache module php

[fotakis]

If it's only available as an apache module, does anyone know how to do it as a cgi module??

Many thanxs for the help in advance,

Try:

Header("WWW-Authenticate: Basic realm=\"MyName\"");
Header("Status: 401 Unauthorized");
