Hello everyone,
I am in panic mode today and would very much appreciate your precious help:
Since three hours now our Java-based Google App Engine application is
throwing AccessControlExceptions when it tries to load a FreeMarker
template. The code of this application did not change for 11 da
see on that part seem to
require some user interaction, which won't work for my use case where an
App Engine app simply wants to retrieve some metrics...
Any help would be much appreciated :)
Thanks,
Holger

High traffic applications are served directly out of the cache within

For low traffic applications first the uploded code has to be prepared

I think, 'deltentries' is just the query and doesn't include the
