How to get updated information with caching enabled every time a page is accessed?

Question

1C-Bitrix

Hi all!
Tell me how to get updated information correctly when accessing a page with caching enabled?
1. There is an element ib;
2. There is HL;
HL stores files uploaded by the user related to the ib element. In result_modifier.php I get info from HL. On the ib element page, you need to update information about uploaded files.
Tell me how to do it right and where to start?

Answer 1

Much depends on the design layout.
If the layout visually allows, move the code from result_modifier.php to the detail.php file of the bitrix:news complex component template (or to a similar file if you use bitrix:catalog). This file is not cached.

Answer 2

And you can reset the cache by tag when updating hl elements
