Changes between Initial Version and Version 9 of Ticket #19949

-              initial
+              v9
 In cases where multiple fallback templates are requested to the template loader (i.e. `django.template.loader.select_template()`) to find the first one available, the cached template loader does not cache non-existent templates, making cached loader "slow" again if every time it has to try looking for a template that's been already found to be missing.

 from django.template.loader import render_to_string
 render_to_string(['missing_template_1.html', 'missing_template_2.html', ..., 'missing_template_N.html', 'existent_template.html'])
+``
+}}}
 When using `django.template.loaders.cached.Loader`, and given that snippet above, and the fact that `missing_template_1.html` ... `missing_template_N.html` do not exist, the filesystem loader or other loaders get hit every time (trying and trying to find already known as missing templates).
