Each collection controls its own cache, customizable
via two parameters that get their default
values from the domain:
cache_size: int = 0
sets the maximum number
of loaded templates in a collection, with a value of 0
meaning no limit.auto_reload: int = 60
sets the minimum number of seconds to wait before
doing astaton the template file to see if it
has been modified. A value of 0 means to do the file system
check on each request for the template.
The collection cache is always on.
If you prefer to run like there was no cache, i.e. reloading
every template each time it is requested, you can set
cache_size=1 and auto_reload=0.
If, on the other hand, you would like to run such that
templates are virtually never reloaded, you can set
cache_size=0 and
auto_reload=60*60*24,
i.e. a sufficiently large number of seconds to wait
between checks.
