Programmaticaly clear webpage cache

Hi
I am using webpage caching and it works perfect. But I want to be able to clear the cache on a per page basis.
Is there a way of doing this without manually search and delete the file?

Why do you need to delete?

For when the content changes before cache expiry

There is no easy way. You need to write code for it.
See cachePage() in system/CodeIgniter.php

In CI3 there is a method to delete cache:
$this->output->delete_cache()

But it seems there is no method in CI4:

Thanks.

One last question.
Is there some sort of table somewhere which matches the cache file with the right url?

I assume CI doesnt loop through all the cached files to see which one to use.

Cached data does not have URI, CI generates a cache key from URI.
See https://github.com/codeigniter4/CodeIgni...r.php#L762

I understand.

But how does CI knows which file to render?
The filenames are random.

They are not random.
The cache key (= filename) is the md5 hash for the current URI.

Thanks,
Solved it by doing:

PHP Code:

@unlink(WRITEPATH.'/cache/'.md5(base_url($slug))); 


Whenever I update a page
