I have a static part which is included on every page (navigation), but takes long to generate. That is why I have set a cache lifetime and a static cache key.
Works fine, until FPC is enabled. Then the block is still generated again for a newly called page and not served from the block cache.
There is this line in
Mage::app() ->getCacheInstance() ->banUse(Mage_Core_Block_Abstract::CACHE_GROUP); // disable blocks cache
What is the reason for this? It makes sense to me to still cache certain blocks, even if FPC is on - because otherwise generation of pages which are not fully served from the cache are slowed down.
- What is the design decission behind that?
- What is a good solution around that?
- Would it be harmful if I just remove this block cache banning?
