Exclude external links from HTML cache?

    I’m running the Avada theme on a website that I maintain, which uses Avada’s built-in Instagram post gallery.

    I’m having some caching issues with the links. Avada looks for new posts and is suppose to fetch the updated image CDN links once a day (The cron does appear to be running). However, the links seem to be getting cached in the HTML and are not updating, leading to that element breaking once the Instagram CDN links expire every few days.

    What can I do to make sure that these external links are never cached in the HTML?

    The links are formatted like so:

    https://scontent-bru2-1.cdninstagram.com/

    The sub domain will change per image depending on where it is served from, but the domain cdninstagram.com always stays the same.

    As far as what I have tried so far: I have excluded “cdninstagram.com” in Cache > Excludes > Do Not Cache URIs. I have done the same in Page Optimization > Tuning > URI Excludes. I have disabled HTML minification and I have also excluded the JS files for that module just as good measure.

    HTML doesn’t appear to be (and shouldn’t be) cached on Cloudflare.

    What can I do to make sure that these links always stay updated? I’m having to manually purge the cache about every two days to keep it updated which I cant do for the long run.

    Thanks!

    no , that won’t work , I guess only solution is purge the cache alone with the update , the only question for that is , you need to find a way to trigger this action , from our plugin , we have purge API can use

    was that instagram section added by something like widget ? or shortcode ?

    Hmm. It’s not a shortcode, so I assume widget? It’s an element within the Avada theme’s page builder so it is built-in functionality to the theme itself.

    I definitely don’t want to flush the entire cache every day if I don’t need to, but I could care less if only the HTML gets flushed each day or even if it wasn’t cached altogether.

    the cache is per page , does that instagram thing show up on all pages ? or only home page ?

    It’s only on the home page, so could I do “Scheduled Purge URLs” for the domain “nfwllc.com/” or is there a better way to handle that?

    yes , you can try that approach first

    Hi again @qtwrk,
    I put this into place a week ago and have ignored it since then because of the holidays. I checked back in today though and noticed that the links are once again broken.

    I looked into the cron events with WP Crontrol and noticed that no cron seems to show up for the scheduled purge. Is this something I still need to configure manually? I’ve not really messed around with cron before past just monitoring for events.

    I left the links broken this time and did not flush the cache, so you can follow the original URL above to see what I am running into (bottom of the home page).

    purge it now , let me check again.

    Purged now. Had to do a Purge All for it to go. Purge this page doesn’t seem to be enough.

    Also added an image above with my scheduled purge settings.

    the external links gives “URL signature expired” error

    remove that schedule purge , I have a simpler idea , please go to Cache -> TTL -> Default Front Page TTL , set it to 43200 and purge all , see how it goes

    Thread Starter rotornut44

    (@rotornut44)

    OK. Got that removed and the TTL updated. Will monitor it over the next few days to see what happens. Thanks!

    you can also try 21600 though

    Hi again @qtwrk

    I made the front page TTL change to 43200, purged all and checked it throughout the week. The links did break again and it never cleared, so I bumped the TTL down to 21600 as you suggested. Checked it again earlier this week and the links were broke again, checked back this morning and they are still broke.

    It’s almost as if the headers aren’t being respected. Not sure what to do at this point?

    I’ll leave the home page as is so maybe you can see something that I’m not.

    frankly say , it’s how/when that CDN image link expires , it could be 5 minutes , it could be an hour , you can keep trying a lower TTL
