Are you by any chance able to tell me if the version of MU you are using includes the WP function 'site_url()' ?

In standard wordpress it s in the file link-template.php…

This function should return the site url with the correct http/https and it is what we use to determine ALL SPF URLs…

Hi,

Thanks for your reply…

I don't know much php but I guess my version of WP uses the WP function 'site_url()' .
I found the file you mentioned in the wp-includes subfolder.

This is the code:

/**
 * Retrieve the site url.
 *
 * Returns the 'site_url' option with the appropriate protocol,  'https' if
 * is_ssl() and 'http' otherwise. If $scheme is 'http' or 'https', is_ssl() is
 * overridden.
 *
 * @package WordPress
 * @since 2.6.0
 *
 * @param string $path Optional. Path relative to the site url.
 * @param string $scheme Optional. Scheme to give the site url context. Currently 'http','https', 'login', 'login_post', or 'admin'.
 * @return string Site url link with optional path appended.
*/
function site_url($path = '', $scheme = null) {
    // should the list of allowed schemes be maintained elsewhere?
    $orig_scheme = $scheme;
    if ( !in_array($scheme, array('http', 'https')) ) {
        if ( ( 'login_post' == $scheme || 'rpc' == $scheme ) && ( force_ssl_login() || force_ssl_admin() ) )
            $scheme = 'https';
        elseif ( ('login' == $scheme) && ( force_ssl_admin() ) )
            $scheme = 'https';
        elseif ( ('admin' == $scheme) && force_ssl_admin() )
            $scheme = 'https';
        else
            $scheme = ( is_ssl() ? 'https' : 'http' );
    }

    $url = str_replace( 'http://', "{$scheme}://", get_option('siteurl') );

    if ( !empty($path) && is_string($path) && strpos($path, '..') === false )
        $url .= '/' . ltrim($path, '/');

    return apply_filters('site_url', $url, $path, $orig_scheme);
}
