Hello @treimiller2018,
Our cache service will honor all cache control headers that are included in the request that is passed by either the application or via htaccess for example. In your particular case the Cache-Control: private header will prevent the page to be cached by our dynamic cache service. Cookies as well are not cached, thus any cookie that you set will prevent the page/request from being cached.

Hello @k3llanved ,
Not to sound stupid, but this is definitely outside my area of expertise and I still require assistance to resolve the source of the dynamic caching issue.
I’ve found and removed the code from the htaccess file that was causing the Cache-Control:private header.
From the CURL report, it looks like there are still two plug-ins that are setting cookies:
Set-Cookie: wccp_pro_functionality=deleted; expires=Thu, 01-Jan-1970 00:00:01 GMT; Max-Age=0; path=/
Set-Cookie: socialsnap_viewed_209150=1; secure
Does this mean that these plug-ins are preventing dynamic caching from working altogether? Or is there some other cause that dynamic caching still isn’t working?
I confirm that we would not cache a page if a cookie is set by a plugin or via htaccess. Seek an alternative to the plugins that set those cookies if you intend to use our dynamic full-page cache.
Best Regards,
Simeon Boev

I have disabled the plugins that were creating cookies on the site (WP Content Copy Protection and Social Snap Plus), cleaned up the htaccess file, and dynamic caching is still not working per the CURL report below.
All we have in the htaccess file is the SiteGround HTTPS enforce code and the standard WordPress htaccess file code.

Hello @treimiller2018,
I have just tested your website and the CURL request is showing the status: HIT
That means the page is properly utilizing Dynamic caching.

The website is served over the CDN edge dynamic caching as well as seen from the results.
You can also verify the page is properly cached by navigating to WordPress dashboard > SG Optimizer > Caching > Test URL Caching Status > click on Test.
If you believe there is still a problem it would be best to post a Helpdesk request with the steps you take to receive that result and we try to assist you further.

Hi @georgiganchev
I just retested the site and the first time I got a HIT as you did, but now I’m getting a MISS. So it seems to be alternating between HIT and MISS.
@georgiganchev
Please hold off on checking the site again. It’s generating an error message so I need to restore it from backup and make the corrections again.
@georgiganchev
Ok,you can check the site again now. The CURL report still shows a MISS on X-Proxy-Cache (see below), but when I check caching status through SG Optimizer > Caching > Test URL Status, I get a Success message.

@treimiller2018
I am unable to replicate the reported issue. When the cache is flushed from the application the first CURL request would be MISS as there is no cache to load from.
The second request would be HIT since the cache is loading.
If you execute new CURL requests without purging the cache you will get x-proxy-cache: HIT
If your issues still persist, please open a HelpDesk request. The SiteGround optimizer plugin is working properly.

Hola, tengo un problema similar, tengo cookies configuradas, por lo cual hay algun plugin que me genera un ciertas cabeceras que no dejan ejecutar la cache dinamica, tengo SiteGround, CDN y SG Optimizer, en las pruebas de SG dice que la web no esta en caché, a continuación el informe de SiteGround.
Tu sitio tiene cookies configuradas y hay un encabezado de control de caché. Debido a esto, tu sitio web no tiene caché dinámica en este momento. Esto se ve en los encabezados al hacer una solicitud cURL, puedes ver un ejemplo a continuación, he marcado el encabezado de cookies y cache-control en negrita:
Tsvetana-Georgieva:~ tsvetana.georgieva$ curl -I -X GET https://www.junkodecoracion.com HTTP/2 200 server: nginx date: Tue, 28 Mar 2023 12:30:20 GMT content-type: text/html; charset=UTF-8 vary: Accept-Encoding expires: Thu, 19 Nov 1981 08:52:00 GMT

He comprobado si esto está definido en el archivo .htaccess, sin embargo, no había nada relevante allí. Esto significa que estos encabezados son añadidos por uno de tus plugins o tema. Puedes trabajar con tu desarrollador en términos de identificar qué plugin o si el tema agrega este encabezado y si esto es algo que se puede ajustar para que nuestra caché dinámica funcione en tu sitio.
Hello @matth86,
Indeed our cache services will not cache requests that include cookies or cache-control: no-cache headers. Take a look at the configuration of the website in question and perform the necessary adjustments to remove both if you intend to use the dynamic cache at its full capacity.

Simeon Boev
Hola Simeon Boev, he revisado todo y no he encontrado nada fuera de lo normal que haga que no pueda utilizar caché dinamico. Las configuraciones de SG tambien estan correctas, revisé el theme (porto) y no veo nada que tenga que modificar, tendrás alguna otra idea de donde puedo solucionar este problema?
Muchas gracias!
Hello @matth86,
Your website cannot be properly cached due to the fact that the application serves a cookie session in the response headers. This can be verified from the following line:
set-cookie: PHPSESSID=6e2057c1b5007080845512275c7272b3;
Sessions are usually created by the installed plugins, themes, etc. You may try and find the plugin responsible for this header by disabling them one by one and testing the cache functionality of the SG Optimizer after each disabled plugin.
Best regards,
Dimo
