Page uncached every single refresh

Hi szmigieldesign,

Does the plugin only works on specific theme? I can not find it in wordpress plugin.

Do you mean optimized files are always miss? or Which page with comment always showing miss?

For status code 403, you could try disable LSCache and see if it still happened.

Generally LSCache exclude can not make cookie excluded works. It should enter in partial of path or file name.

Hi,

it’s premium plugin that extends WP comments functionality – https://thrivethemes.com/comments/

I’ve had a situation when comments didn’t load (they are being pushed through REST API, via delayed JS). Upon investigation I’ve found that they didn’t load because of certain cookie expiration (I believe it’s tve_secret). So I’ve added this cookie as an exception to LSCache.

It’s been few days now and everything seems to be fine. I’m only worried about

Page uncached by LiteSpeed Cache 1.6.7 on 2017-12-20 09:00:09

In website source code. Timestamp changes whenever I refresh the page, even when I’m logged out. I used to see “Page cached” and it’s uncached now. I wonder if it’s related to this cookie exception? Does it mean that the page is being re-rendered by LSCache every time someone visits it?

Hello.

Here is the problem: when you add a cookie to the Do Not Cache Cookie list, what you are really saying is “Do not cache pages that use this cookie.” So, you are correct: that timestamp indicates that the page is no longer being cached.

Hai can take it from here with some suggestions ??

Hi there,

As you set that cookie to no cacheable, that makes your whole site no cacheable as that cookie doesn’t have a subfolder path restriction.

You don’t have to set wp-json to exclude. Try to turn off REST cache.

However, bypassing it is not the solution. We will try to reproduce that 403 and figure out the way to fix it.

I’ve set a debugger copy on a subdomain:

https://debug.szmigieldesign.pl/blog/najlepsza-wtyczka-cache-dla-wordpress/

The problem should appear again in approximately 24 hours. Feel free to check.

I’ve removed the cookie exception for the main site and switched off REST caching. We’ll see if it resolves the problem or not.

The problem is back roughly about 24 hours after the cache was built.

You can check for example:

Comments won’t load with 403 while requesting:

https://szmigieldesign.pl/wp-json/tcm/v1/comments/2643?_=1513860164604

Response:
{"code":"rest_cookie_invalid_nonce","message":"Kodem jednorazowy z ciasteczka jest nieprawid\u0142owy","data":{"status":403}}

REST API caching is off, cookies are being cached.

That 403 is caused by the request’s nonce expired. You shouldn’t cache that rest call. It needs to be converted to ESI.

Could you please elaborate on this matter? I’d like to pass this information along to Thrive Comments developers (I believe it’s not just a matter of switching ESI on in LSCache?).

By making it ESI, it will be separate cache with separate TTL, also can be purged separately. For WP’s nonce, this is the best solution.

Awesome, thanks. I’ll pass this along.

Is there any workaround for now? Just don’t cache “/blog/*”?

Yes that might be the only way for now.

How can I add an exception to uncache only those pages that url contains /blog/, but not the main blog page? Ie. /blog/article1, /blog/article2, etc.

Unfortunately adding

/blog/*

To URL exceptions list doesn’t work.

Do not add *
