Serve resources from a consistent URL and PageSpeed

    I have been using GT Metrix and Page Speed to measure my site performance as I tweak Litespeed Cache. I now wonder if PageSpeed is helpful or not. I receive an F for Serve Resources From Consistent URL, since it says the same URL is listed for my server and the CDN. But when I look at the page source, I do not see duplicates with the two URLs. But if I exclude the server URL in Litespeed Cache, the results are an A and the page loads faster. How can Pagespeed see inconsistent URLs if I can’t see them in the page source?

    How can there be inconsistent URLs served when I can’t see them in the page source?

    https://www.sd-wan-experts.com/min/fe426.js

    I can easily exclude the page, but I just want to understand.

    The page I need help with: [log in to see the link]

    This happens because the fe426.js is sent by http2 push. While our http/2 push is before cdn. This is what we should improve to avoid http2 push when its served by cdn.

    Thanks for your feedback. Will fix.

    Hi, sgarson

    Let me see if I understand the issue.

    You are getting an F for Serve Resources from Consistent URL, which indicates that the same file is being requested from two different locations, presumably the two JS locations you linked to in your question, correct?

    But when you look at the source, you only see one of these JS files? (I looked at your source, and I only saw the CDN version).

    When you say “exclude the server URL in Litespeed Cache” what, exactly, are you excluding? The URL to the www.sd-wan-experts.com JS file?

    If you can clarify those couple of questions, then I can help you better. Thanks!

    Oops. Didn’t see Hai beat me to the reply. If that solves your problem, please feel free to disregard my questions!
