cache_page decorator doesn't work for cross-browser

[HoangYell]

What is the issue?

• With the same URL, I made 2 requests (1 Postman, 1Firefox), but the second request was not cached

The root cause:

• First load using Postman:
  • default header: Accept: */*

• Second load using Firefox:
  • default header: Accept: 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8'

=> First load's cache_key != Second load's cache_key

Thanks for this ticket, however I don't think you've explained the issue in enough detail to confirm a bug in Django. As far as I'm aware cache keys don't vary on the ACCEPT header unless you explicitly add it to the VARY. In such case it works as expected. Can you provide more details and a sample project?

Thank you, Seem like I don't understand enough about VARY :)

For those who are facing the same problem as me. here is an easy solution:

In settings.py

import django.utils.cache
django.utils.cache.cc_delim_re = re.compile(r"(?:\s*,\s*)|(?:Accept)")
