Support » Plugin: WP Engine Advanced Cache » Compatibility

  • Resolved aggk



    This plugin looks great! It´s a feature that I have really missed at WP Engine.
    Are there any known issues, anything to watch out for?
    Will everything work exactly the same at WP Engine only with optional extended cache timeout?

    Awesome! I am glad you find it useful!

    The only currently known issue, which will be resolved in 1.3, is that on the cart and checkout pages in WooCommerce, browser headers are added which can mess with removing things from cart. It’s a browser side issue, not server side though, but I have a fix going out soon.

    Other than that, everything should work as expected. WP Engine purges the cache on most updates, so everything should behave as it presently does, just with longer cache times. If you see anything weird though, please let me know and I’ll be happy to take a look!

    Thank you,

    I´ll be sure to install this on all our sites at WP Engine…

    Still confused why WP Engine would choose a timeout value of 10 minutes as default?
    …cache/speed is awesome at WP Engine but we create corporate sites that mostly consist of pages that are rarely updated.
    Since these sites are not very “high traffic” I always felt we could never take advantage of the speed that WP Engine can deliver when things are cached, especially for anything a few clicks away from the start page.

    Are there any disadvantages from choosing three weeks instead of 10 minutes for “static” content?
    …seems to me like WP Engine would save huge system resources if this where the default value instead.

    Are “Last-Modified Headers” activated by default at WP engine without this plugin?

    Great! Let me know if you see anything out of the ordinary, or any functionality you’d like and I’d be happy to see what I can do!

    The 10 minute config has existed for a long time from when the logic was that if there were any issues with cache not being purged, then it would kind of organically purge. I don’t think it’s too big of an issue anymore, hence why I made this plugin. I am hopeful that a change goes through as the WP Engine platform evolves that optimizes the cache further, but I know there is a lot of stuff coming up that should make it matter less.

    The only disadvantage would be content that is updated but not associated with something that WP Engine purges automatically, then it wouldn’t update on the page. I haven’t seen anything like this in my testing, so I wouldn’t be too worried. If you’re not seeing any weird things with cache at 10 minutes, you probably won’t see it at a longer time.

    They are not, last-modified is something I built in specific to the plugin. It is really only leveraged by the browser currently, but I am hopeful that it’ll be more useful soon with maybe varnish or a front end CDN system.
