This issue is that even though I defined an alternate index page in my .htaccess, when I add a caching plugin it ignores this redirect.
So if the plugin is not enabled – then my alternate index page works, but the moment I activate the plugin then it ignores the request and reverts back to the default index.php page.
This seems to be the case for most caching plugins I researched but I might be mistaken which is why I wanted to ask the question here.
I really want caching, but then I also need to define an index page other than the /index.php that is my current default.
Thanks again!
