Nginx fastcgi cache problem

Dear support,
Mobile and Desktop home pages are mixed from nginx fastcgi cache…
in other words when access to mobile page first, home page on desktop
is mobile page, and when access from desktop first, home page on mobile
device in not mobile page.
How to resolve this issues.
Thank in advance
BR

Dear Anamaria,
Thank you for your reply.
I will try to implement this code into nginx-helper plugin, and inform you about it when done.

Thank you a lot.
Best Regards

Dear Anmaria,

I tried to implement code into nginx-helper
but I have a errors..
I think that version of current ngnix-helper is different
from your url link manual.

Does your team know how to do this?
