@Tabrisrp Thanks for the PR. During exploratory testing, can see that Purge this URL from the Admin bar at page view or clear this cache from the posts list is not working (i.e not setting cache header to Miss) when permalinks without / i.e /%postname% However, it is working when permalinks with/ i.e /%postname%/. can you please check 🙏

I updated the code to add a trailing slash to the URL to purge

@Tabrisrp Thanks for the update. can still see the problem on the test site using the latest version of the PR. can you please check 🙏

[Tabrisrp]

I can't find the reason why it's not working without trailingslash in the code itself. There is nothing that should impact it, looking at their code: https://github.com/spinupwp/spinupwp-plugin/blob/62ae3ec7c53f602f80cd10c742fae6c361c790f4/src/Cache.php#L289

We might need to ask them if there is a reason on their side

@Mai-Saad, @piotrbak, would it make sense to close the issue as is and open a new one to identify the issue with trailing slash? As this probably needs discussion with Spinup and/or R&D?

@piotrbak, do you have a contact at Spinup we could reach out to?

[Mai-Saad]

@MathieuLamiot I am fine with that, can execute the test plan only while Permalinks having / for now

[piotrbak]

@MathieuLamiot @Tabrisrp @Mai-Saad Agreed, let's do it like that. As soon as the issue is opened, I'll reach SpinupWP and ask them to collaborate there

[MathieuLamiot]

Ok, @Tabrisrp can you open an issue? I think you have more insights on the matter :) Moving this to "Ready for QA" in case there are other things to check :)
Thanks!

Working as expected with the following notes.

• on the trunk with spinupWP (preload off)=> it seems they don't differentiate mobile from desktop
  1- Enable separate mobile cache
  2- clear cache from admin
  3- visit the desktop of the page => cache miss
  4- visit mobile of same page => cache hit
  => As per discussion, SpinupWP does not provide this option
• edit post => clear whole cache (same on trunk and even without wpr)
• switch theme => not clearing home hit header ( UI is correct but the cache is hit, same on the trunk but without wpr cache will be miss in this case), it will cause UI issue even on the trunk while RUCSS is on due to Used CSS isnot automatically generated for home page when switch theme while preload is off #6076 (comment)
