I’ve started using Rails.cache, specially Rails.cache.fetch. This gives  
me some log entries I’m a little curious about - I hope someone can poke  
me in the right direction.

Examples:

1. 

Rails.cache.write(‘testing’, ‘test value’)  
Rails.cache.read(‘testing’)

Gives these log entries:

Cache write: testing  
Cache write: testing  
Cache read: testing  
( Why the two writes? )

1. 

Rails.cache.fetch(‘testing’) { ‘test value’ }

Gives these log entries:

Cache read: testing  
Cache write: testing  
Cache miss: testing ({})  
Cache write: testing  
Cache write (will save 0.00ms): testing  
( Miss after it is writtin? And then to extra writes? )

Best regards  
Rudi

I’ve narrowed it down to situations when memcache store is used.

I think somehow the @logger\_off property in active\_supports cache.rb is  
ignored when used with memcache?

Have anybody else experienced something similar?
