Description
Fixes #6281

The page cache saves Response data before running after filters.
So response headers added by after filters and response body changes by after filters will be lost.

Since the issue affects the operation of the SecureHeaders filter, it seems to me that it would also be correct to return the Response in the SecureHeaders::after() method.

What do you mean?
What's the difference between to return the Response in the SecureHeaders::after() and not to return?

@kenjis If we are targeting the implementation of PSR-15 in version 5, then it would be logical to prepare the codebase for the correct behavior. So that it doesn’t work out, as with legacy 3.x, when, with the transfer of the code base from 3.x to 4.x, the code started to work incorrectly or not as intended.

But yes, within the framework of the current concept of the framework, my proposal does not make sense.

@iRedds I got your point. But I think it is related not only SecureHeaders but also all after filters.
The after() method should always return ResponseInterface.
And if we change the API, at least we must go to 4.3 branch.

We can't do anything in this PR.

A few typos then looks good! Thanks for adding the explicit docs.

Are you certain that 0 indicates "don't cache"? Sometimes it means "never expire".

is it means that cacheTTL value is reset in every run?

Yes.

$cacheTTL will be set by a Controller.
