Frage: Lässt sich Etherpad in einem Managed Webspace auf einem eigenen Managed Server betreiben? Recherchiert, mit einem Befund, der die Sache anders kippt als erwartet. Machbar, ja: - Hostsharing erlaubt ausdrücklich eigene Serverdienste (Daemons) im Managed Webspace gegen ein RAM-Kontingent, und Installationen im Userland — Programmiersprachen, Webserver, Datenbanken. - Node.js wird ausdrücklich unterstützt. Der Haken sitzt beim Transport: Der dokumentierte Node-Weg läuft über Apache mit mod_passenger, und Passenger unterstützt Websockets auf Apache NICHT (nur Nginx und Passenger Standalone, sagt Phusion selbst). Socket.io fällt dann auf Long Polling zurück. Root gibt es auf einem Managed Server nicht; ob die Apache-Vhost-Konfiguration ein Upgrade zu einem eigenen Port durchreicht, ist die offene Frage — deshalb steht der Knoten auf [!]. Entscheidend ist aber, dass unsere Anforderung davon gar nicht abhängt: Die 2 Sekunden brauchen keine Websockets, sondern die Hoheit über die Konfiguration — Export-Rate-Limit oder ein postMessage-Plugin. Beides ist auf einer eigenen Instanz reine Einstellungssache, unabhängig vom Transport. Ein Etherpad, das intern nur pollt, liefert uns trotzdem alles, was wir wollten. Geprüft: 121 Knoten, keine Warnungen.
