How to cache a single wordpress template?

Question

Server optimization

Good afternoon.
There is a site on wp, 500+ pages.
The main page for mobile devices should be different from the desktop version.
At what to differ cardinally.
Therefore, I decided to get out of this situation in this way:
In the main page template - page-home.php I wrote a simple condition:

<?php /* Template Name: Home */ ?>
<?php
if(wp_is_mobile()):
  include_once("page-home-mobile.php");
else:
  include_once("page-home-desctop.php");
endif;
?>

Now different templates are opened for different devices. But there were problems with the caching plugin (wp fastest cache), it cached the page and always gave one option: either the mobile version or the desktop. It shouldn't be like that.
Without caching, the download speed is not encouraging, as there are a lot of database requests on the page.
Is it possible to somehow cache individual php templates? Maybe there are more serious plugins that allow you to manage caching?
upd: "cached" means creating a static copy

Answer 1

You will need to look at the caching plugin code and find the place where you can turn it on and help it understand that if we have wp_is_mobile() true, then we take (or create and take) the mobile cache, if false - the desktop one. If their caching method through mod_rewrite is used, then the settings of these rewrites will also need to be tweaked, at the server level you define desktop / mobile.
The description of the plugin says:
That is, the plugin already knows how to distinguish between devices, by definition. It might be worth looking to see if he has hooks there.
