How do i can disable cache in /wp-admin/* – SEO

Reason, why i need disable cache:

When i create post or page. It caches its. If i create second post or page, then it updates old post or page.
When i disabled cache for each pages, this bug was fixed. Although i need cache for SEO.

So, i need disable cache only in admin pages.

.htaccess

<ifModule mod_headers.c>
  <filesMatch ".(ico|pdf|flv|jpg|jpeg|png|gif|swf|woff2)$">
  Header set Cache-Control "max-age=2592000, public"
  </filesMatch>
  <filesMatch ".(css|js)$">
  Header set Cache-Control "max-age=86400, public"
  </filesMatch>
  <filesMatch ".(xml|txt)$">
  Header set Cache-Control "max-age=172800, public, must-revalidate"
  </filesMatch>
  <filesMatch ".(html|htm|php)$">
  Header set Cache-Control "max-age=1800, private, must-revalidate"
  </filesMatch>

  <FilesMatch ".(js|css|jpg|png|jpeg|gif|xml|json|txt|pdf|mov|avi|otf|woff|ico|swf)$">
  RequestHeader unset Cookie
  Header unset Cookie
  Header unset Set-Cookie
  </FilesMatch>


  # Guarantee HTTPS for 1 Year including Sub Domains
  Header always set Strict-Transport-Security "max-age=31536000;"
</ifModule>

function.php

if (is_admin()) {
      header('Expires: Mon, 26 Jul 1997 05:00:00 GMT');
      header('Cache-Control: no-store, no-cache, must-revalidate');
      header('Cache-Control: post-check=0, pre-check=0', FALSE);
      header('Pragma: no-cache');
}

My code in function.php don’t working.

    Header set Cache-Control “max-age=86400, public”

    I’m afraid that any cache headers set in .htaccess have priority, and it is impossible to override them in PHP.

    The only solution that I can think of is to disable the caching setup in the .htaccess and manually set the headers in each file. It’s a pain, I know, but it’s all that I can fathom.

    The below answer will set caching to the browser default, which I assume is not what you intend.
