使用PHP的AJAX代理,是否可能?

In reference of my other question: Context-aware AJAX call in a modular site , is it possible to set up an AJAX proxy in a convenient way?

I'd wish to make AJAX requests with dynamic url without tainting the JavaScript code with server-side PHP instructions, computing the right path for the ajax php file in a modular Apache/PHP/MySQL site, a rough CMS written by me. In other words, the site has plugins and components with their own folder structures containing their CSS, JS, and PHP and I have functions to retrieve their folder dynamically. I'd wish that:

$("#mydiv").load(siteRoot + "/ajax.php?plugin=datagrid&
action=myaction&... other params...");

will instead call (with the URL computed server-side by PHP):

{siteRoot}/components/datagrid/ajax/myaction.php?... other params ...

(obviously with all the possible checks against injections, CSRF and other hacks).

    /ajax/get.php file should look something like this:

    $plugin = $_GET['plugin'];
    $action = $_GET['action'];
    $get = array();
    foreach ($_GET as $k=>$v) {
        if($k!='plugin' && $k!='action') {
            $get[] = "{$k}={$v}";
        }
    }
    $url = 'siteRoot/components/'.$plugin.'/ajax/'.$action.'.php?'.implode('&', $get);
    
    header("Location: {$url}");
    

    Of course, you need to add some security checks to above code

    EDIT: The downside is that it won't work for sending POST requests
