Varnish create new cache for each browser

[killday]

Apache + SSL + Varnish.

For each separate browser  Varnish create a different version of each page. So each new user is visiting slow version until he visit the same page in the same browser.

Workaround was to disable Vary cookie and cache of static content in which the cookies are included too. No luck till now.

Hi @killday 

This is because of your backend is not sending  User-Agent HTTP header  so i think you should check this for more information you can check varnish-cache-cache-only-seems-warmed-on-each-browser this. 

Hope this answer help.

Hi @shubham_khandelwal1 ,

Thanks for your suggestion but as I can see my backend is sending the User-Agent HTTP header or I'm wrong.
