Default Value for Cache TTL

[miqrogroove]

My recent ticket #1640 was closed for an invalid reason.

providence/app/helpers/post-setup.php

Line 85 in 0dc8e52

define('__CA_CACHE_TTL__', 3600);

This is the line of code that causes my user session to fail every hour.

This value should be something like ten times larger.

Steps to reproduce this problem:

1. Leave your Providence instance unused for one hour to allow the cache to expire.
2. In setup.php configure the TTL to a lower value such as 60.
3. Log in to your Providence instance.
4. Set a timer and don't click anything else for 2 minutes.
5. After the delay, click on one of the links on the dashboard.

Expected result:

Link clicking should not be compromised by reasonable default values.

Actual result:

The click fails and redirects to the login screen.

Workaround:

In further testing, I found just setting the TTL to 36000 fully mitigates that problem for me.

Environment:

Providence dev/php8 pulled last month.
