response_hit_indication header value is true when "found" is false

[sumandari]

hit_cache doesn't reflect the found value

When the key expires, the found value will be False, but apply_caching method after always give 'True' when invoked in after_request_funcs

flask-caching/src/flask_caching/__init__.py

Line 418 in 494d498

def apply_caching(response):

'hit_cache': 'True'

expectation:
when found is False, the header will be false in after_request invocation

Environment:

• Python version: 3.11
• Flask-Caching version: 2.3.0

Also, every time the cached function is called, after_request_funcs grows in length?

flask-caching/src/flask_caching/__init__.py

Line 423 in 494d498

self.app.after_request_funcs[None].append(apply_caching)
