# Questions about caching

 * Hello. I have a few questions about this plugin:
 * 1. Is the plugin free, or does it require payment? [This page](https://premium.wpmudev.org/project/wp-hummingbird/)
   seems to indicate that there is a 30-day free trial. After that 30 days, does
   it require payment?
 * 2. I see the plugin offers page caching, which, “Store static HTML copies of 
   your pages and posts to reduce the processing load on your server and dramatically
   speed up your page load time.” What if I make a change to one of those pages–
   how will I ensure the user’s browser loads the newly edited page, rather than
   the cached HTML copy?
 * 3. I see the plugin offers browser caching: “Store temporary data on your visitors
   devices so that they don’t have to download assets twice if they don’t have to.”
   I have a similar question. If I edit one of these files (e.g. CSS file, JS file,
   etc), how will I ensure the user’s browser loads this new file, rather than the
   old, cached version?
 * Thanks.

 * Hello there
 * I trust you’re doing good today! 🙂

    HummingBird has a free version (the one here in wp.org) **and** a pro version,
   which you can get when you acquire the premium WPMUDEV membership (includes 30
   days of trial). For more info, please have a read in the following article: [https://premium.wpmudev.org/blog/wpmu-dev-premium-wordpress-plugins-for-free/](https://premium.wpmudev.org/blog/wpmu-dev-premium-wordpress-plugins-for-free/)

    Page Caching is providing 3 ways for that: _Manual_, _Automate_ and _None_.
   [https://monosnap.com/file/3S4eS30Vr4vljbaxAAo3MPusID6YBF](https://monosnap.com/file/3S4eS30Vr4vljbaxAAo3MPusID6YBF)
   You can set it to Automate and rest assured that when a page is being edited,
   a new cached copy will be generated.
 * 3.
    Browser Caching can’t be cleared from your end, but only in the browser itself.
   Using it in combination with Page Caching though, won’t create any misbehavior
   though, especially in cases of page/post edits. Also dynamic generated assets
   use some versioning in order to surpass that. It’s always preferable though, 
   to activate all caching mechanisms after web development is over.
 * Hope that was some help!
    Take care, Dimitris
