[CalendarServer-users] Reverse proxy issue ?

[Bastien Semene]

Hi list,

To compensate a lack of IPs I set up a reverse-proxy to handle some 
https:// connections. It includes access to the calendar server.
Calendar server is reachable at https://xxx.com/calendar/ and the proxy 
reaches caldav at the internal URL : http://calendar.xxx.com:8008 
(directives at the bottom)

I can see the the calendars without problem, but I have the following 
issue :
- When creating a new event, I must manually refresh it to see the 
modification.
- I can't delete an event (logs are below). Note that in the logs when 
DELETE fails the first part of ics id is missing.

Is there some particular configuration needed ? Am I doing something 
wrong ? Is it possible to have a reverse-proxy ?

Logs :
You can see access from reverse proxy or host by its IP (respectively 
10.1.8.1 and 10.1.8.220).
