Caching while the whole back end is in maintenance mode
|
|
We have periodic code updates on our drupal based back end.
The back-end servers have a maintenance mode that will return a 503 for
HTTP requests without cookies.
The code updates sometimes take several hours - enough for the cached copy
to expire. Grace mode appears (sorry; single data point; this is what the
developers told me) to time out after an hour no matter what we set it to
in vcl_recv/vcl_fetch.
Is there a better approach to have everything that's cacheable available
for a few hours? What are others doing?
TIA,
--- David
