WebP fallback

    Hello,

    Love the addition of webP to LiteSpeed Cache but you should be aware that not all browsers support it yet: https://caniuse.com/webp/embed/

    So, I think a fallback to those browsers would be best practice. Not everybody know that and most likely won’t understand why there images are missing.

    Hi, Yoav.

    Yes, we are aware of this limitation, and a callback to jpg (or png) is exactly what is done in those cases.

    Are you observing something different?

    Hey Lisa,

    In a matter of fact, the fallback doesn’t seem to work when browsing on MS Edge: https://zupimages.net/up/17/44/gtwb.png

    But, otherwise, works without any hiccups.

    Hmm. Ok, thank you for reporting it! We’ll have a look.

    I’m trying to recreate the issue, but it works for my test site on Edge and Firefox. Can you share a URL where it is not working?

    Thanks!

    When the browser which doesn’t support WebP visits your site, a non-webp cache copy should be served as it will have different vary copy.

    In your .htaccess there should be one rule which adds the vary ‘+webp’. Can you check if its there, and share the debug log when you visit via MS Edge? Or give more detail so we can have a look.

    Here is the URL: https://goo.gl/wgD9c7

    I do see the specific line in the .htaccess indeed.

    That page is strange. Can you create a tix or paste the debug log when you access via firefox/safari? Thanks.

    That’s weird! Glad it works for you; maybe my computer is messing around…

    I have no idea how to get what you requested :/

    I mean the page doesn’t have expected footer comment. Can you paste the log as I mentioned? Or a ticket.

    From your debug log, nothing is wrong. Please create a ticket.

    Well, looks like I can reproduce the issue now. Found the bug. It only happens for img src, while not for srcset.

    Will fix in this week’s release. Thanks a lot for the feedback.
