JotCache Frequently Asked Questions

This part od Q & A serves to clarification / explaination of different functions of JotCache extension.

Can I cache separatelly pages by browser type ?

 

In case when you need to cache different page content having the same load URL (e.g. different content generated  for some browser types (IE8, IE9) or browser width (desktop, mobile)) then you can use JotCache Browser split function. You can use this setup for setting which browser types are included in common cache, which other can have individual cache storage and which one can be full excluded from page caching.

NOTE : Browser type is derived from user browser agent string during page request.
