Masking logout URL

The primary goal is to hide that the site is driven by wordpress. I’ve got the login part all locked up, but the logout URL still has those blasted wp delineators that give away it’s a wordpress site.

Is there a way to somehow mask this URL? Perhaps by a conjunction of custom redirect where the client-side link goes to www.site.com/logout/ but something in functions.php rebuilds the actual logout link?

I’ve tried variations of wp_logout_url('$index.php') but this only redirects. I’ve also tried

add_filter( 'wp_logout_url', 'cusotm_logout' );
function cusotm_logout() 
{
    // set your URL here
    return 'http://www.site.com/logout/';
}

Not only does this last one not work, it also appends title= to the end of the URL. I’m not sure if the logout doesn’t work because of that or if the function itself is the wrong approach entirely.

I only use plugins if I absolutely have to. Looking for a self-managed solution… without needing to mod_rewrite if at all possible.

Replacing just the URL is not enough. You have to tell WordPress what to do with the new URL.

Sample code, creates a log-out URL like example.com/logout=1 and redirects to front page or custom URL after logging the user out:

add_filter( 'logout_url', 't5_custom_logout_url', 10, 2 );
add_action( 'wp_loaded', 't5_custom_logout_action' );

/**
 * Replace default log-out URL.
 *
 * @wp-hook logout_url
 * @param   string $logout_url
 * @param   string $redirect
 * @return  string
 */
function t5_custom_logout_url( $logout_url, $redirect )
{
    $url = add_query_arg( 'logout', 1, home_url( "https://wordpress.stackexchange.com/" ) );

    if ( ! empty ( $redirect ) )
        $url = add_query_arg( 'redirect', $redirect, $url );

    return $url;
}

/**
 * Log the user out.
 *
 * @wp-hook wp_loaded
 * @return  void
 */
function t5_custom_logout_action()
{
    if ( ! isset ( $_GET['logout'] ) )
        return;

    wp_logout();

    $loc = isset ( $_GET['redirect'] ) ? $_GET['redirect'] : home_url( "https://wordpress.stackexchange.com/" );
    wp_redirect( $loc );
    exit;
}

As plugin on GitHub, because this is pure plugin territory. And you cannot really hide WordPress.

it also appends title= to the end of the URL

I guess the problem is markup like this:

<a href="https://wordpress.stackexchange.com/questions/76161/<?php echo wp_logout_url(); ?> title="Log out">Log out</a>

Note the missing ".
