Question AWSTATS 404 site not found

[Danny325]

I handle all uris over my frontcontroller and php scripts like that it was necessary to add:

if (!-e $request_filename){
   rewrite ^(.*)$ /index.php break;
}

Now if i try to open the awstat ui, .../plesk-stat/webstat-ssl/ i get my custom 404 error page.

Is there any clever way handle only the affected uri with nginx ?

EDIT:
Meantime i added before something like:

if ($request_uri ~ "^\/plesk-stat\/$"){
    break;
}

Any better solution ?
