Hi,
Thanks for all the information.
My Blog have less than 1% of mobile users, but sometimes, the static HTML file was the mobile version of the blog, witch was served to all desktop users.
I just added the define(‘DONOTCACHEPAGE’,’true’); in the funcions.php of my mobile theme and the problem was solved.
But it only solve the problem in these type of cases that very few mobile users access the blog. In a heavy-traffic mobile blog, it can cause some performance problems, provided the mobile users needs to render every page as if no cache is made.
I think the solution is to make a different static HTML file for each user agent. The caching will be done a lot of times, but will be done correctly.
Best Regards!
