# File – Cache Management

 * I have a website that uses an API to login users.
 * When the user is logged in the header links update.
    But with this plugin, they
   don’t update.
 * I use this plugin for all our clients and was wondering if there is a way to 
   disable the cache for a specific file. Header.php for example.
 * Or Can I trigger a flush when the user is logged in, for example, call a function
   in my functions.php file?

 * Do you mean that they don’t ever update at all? Or that they don’t update until
   the newly-logged-in user visits another page?

 * Our plugin has a hook to wp login process action `set_logged_in_cookie` in `inc/
   vary.class.php`, to set a cookie which can make the logged-in users get a separate
   cache than guest visitors.
 * If your API honors that hook, it will set that cookie. Are you using any other
   ways to login?

    They don’t update until
   they visit a page that hasn’t been viewed yet.

    It’s not using any 
   Wp login they don’t have an account for WordPress the account is stored off-site
   and validated in functions.php.
 * Is there a function to trigger a flush from functions.php.

 * Hi, [@beansandrice](https://wordpress.org/support/users/beansandrice/)
 * Yes, there is a function to trigger a flush available in our API, but I wouldn’t
   recommend that approach.
 * The best way to handle this, I think, is for you to have separate cached copies
   of the page: one for logged-in users, and one for non-logged-in users. If you
   can set a cookie to distinguish who is a logged-in user, then LSCache can be 
   configured to create a cache vary on that cookie.
 * You’d need to add a line to your .htaccess like this, where “api-login-cookie”
   is the name of the cookie used by the plugin:
 * `RewriteRule .* - [E="cache-vary:api-login-cookie"]`
 * We discussed a similar situation in [this post](https://wordpress.org/support/topic/not-caching-pages-for-specific-users/#post-10485187)
   recently. And [this wiki](https://www.litespeedtech.com/support/wiki/doku.php/litespeed_wiki:cache:developer_guide:cache-vary?s[]=cookie#how_to_instruct_the_server_to_use_a_custom_vary)
   goes into some detail about how it works.
 * Let us know if you have any questions!
