I am writing a plugin where I want to read user agent and send custom headers back on certain agents. Unfortunately however several people have the W3 Total Cache plugin and what it's doing is that, when I have a condition that sends back the custom header, it then sends back that custom header for ALL user agents, not running my event logic. I tried to load my event with...
...but W3 Total Cache intercepts via .htaccess or by some other mechanism. Unfortunately I have to do it at the
plugins_loaded level because I need to query
How can I make my plugin work even if W3 Total Cache is engaged?
