Support HTTP Etags for frabxml/ical/... exports

[johnjohndoe]

Problem you are facing

Client applications which retrieve the schedule data from an Pretalx instance do need to load the file everytime. This increases the traffic for both the server and the client.

Possible Solution

The Pretalx API should be able to provide and consume HTTP ETags.

Context

I am maintaining the EventFahrplan project which consumes schedule data from the Pretalx API.
The current EventFahrplan implementation compares the old and the new schedule to find out whether it has changed. This could be done by the server using ETags.

I'm assuming you mean the exports, not the API?

Nice. Thank you for the quick action.
Just to clarify: this is not yet live for MRMCD 2018, correct?

[rixx]

Yeah, that is correct. You can be sure the change will be included in all instances running the upcoming 0.8 release and above, soon.
