It is sad to realise that this issue has been first raised 7 years ago!

I am having this issue with device detection as I use both WP Rocket (for overall optimization of CSS/JS) and Cloudflare. Well, in this scenario and Varnish the end client is not served the right (static) file, nor the correct file it is generated. e.g. if the first person to access a page has a mobile client, then the mobile version will be generated, else no luck.

It is imperative that you address this issue. Our traffic is about 80% mobile these days.

Having positive experience with Cloudways staff, I am confident that they can implement it in no time.

Here follow a couple of links:

Please add an additional configuration layer for varnish to give the ability to the user to decide whether to service from varnish cache or the webserver depending on the values stated in the HTTP request header. This can be done with the W3TotalCache plugin (cookie-based caching - maintains separate caches for cookies)

For i.e. If the website is accessed by a mobile device (can be determined by the request header), serve from the mobile cache. If not, serve it from a different cache, etc.

This is very important if the website is specially optimized for mobiles compared to its counter part desktop website.

Google page insight reports having too many html tags (DOM depth, DOM length) for mobile pages even if you use responsive design to go from desktop website to mobile website. So what WordPress developers can do is, remove the desktop load by removing the HTML tags that are not neeed for the mobile website. But in order to do this, varnish cache should be able to have multiple caches.

This is easily achievable in wordpress if you use W3TotalCache plugin. But varnish is a reverse proxy cache which we will have to configure separately.

Thank you.

This is very important. There are more people using mobile than desktop

Mobile eCommerce is more and more import than before, so many eCommerce will optimize their website for mobile devices, one of the best ways is to develop a new layout for mobile devices.

If the webmaster wants to set Varnish cache for their Magento 2 website and if the website has more than one layout (one layout for a desktop computer, one layout for mobile devices(smartphone, tablet, etc.)), then they need to set mobile device detection for varnish cache.

In our opinion, set varnish mobile device detection for Magento 2 website is very very easy, because of all the necessary info are predefined in the exported VCL for varnish from Magento 2 admin, so we just need to
1. Export VCL file for varnish from Magento 2 admin, and
2. Upload the exported VCL file to the server
to set mobile device detection for varnish cache.

Thank you in advance for your considering to let us set varnish mobile device detection for Magento 2 website.

Best regards,

Mobile devices revenues will overtake desktop revenues, so device detection in Varnish is really very import.

M-Commerce is very very popular now, so always more websites have a mobile layout. If there is no device detection in Varnish, then fewer people will use the service from Cloudways.

Hello,

when can you add this feature?
I think that device detection is very important.
