[TYPO3-mvc] Cacheable and non-cacheable actions in extbase

[Sören Kracker]

Hi list,

I've got an extension which makes use of ml_geoip. I've got problems 
using and understanding how to setup the cache in my extension and need 
hints for best practice.
initAction checks if visitor's country is already present in session. If 
yes, it forwards to listAction, otherwise to geoipAction which finds out 
about the visitor's country, writes it to the session and then forwards 
to listAction. So listAction receives always the visitor's country and 
could be cached for each country.
Reason for this is that depending on the country other records should be 
selected from the database.

I've set up actions init and geoip (non-cacheable) in default plugin and 
list (cacheable) in another plugin.
Is this the recommended setup? Or could/should I set this up in another 
way? And which part exactly is cached then? I'd assume that changing 
something in the controller action would have no effect if there is 
something cached, but it does. Performance isn't that great (>2s per 
page) although there are just a few records. But maybe this is because 
of extbase in general? Or is it Fluid? Where could a bottleneck be? In 
the controller from Init to end of List action takes only 1ms.
TYPO3 Profiler extension shows no_cache = 1 on the page with my 
extension. Shouldn't this be 0? Any help/hints appreciated!

Kind Regards

Sören
