Description Dirk Wiesenthal

Btw. can't we store the E-Tag and make conditional HTTP requests?

+++ This bug was initially created as a clone of Bug #39693 +++

I've changed in one App Center session the autostart behavior for a Docker App:
 - Opening App details
 - changing autostart
 - apply
 - opening App details
 - changing autostart back
 - apply

It looks like the index.json.gz was downloaded two times and a lot of Apps are loaded and unloaded. The logfile part is not from the whole session, only from the actions described above.

Fixed in
  univention-appcenter 5.0.19-18.77.201511302249

/var/cache/univention-appcenter/.etags added. Keeps track of other supra files and does not download it again in case of 304.
