Hi everyone, I want to cache png images with memcached and serve with nginx. I configured nginx and i could write images to memcached. When i try to read this images from cache with memcached client i can. But when i try to read this images from nginx, broken images comes. For example : I put byte array to memcached with 115832 bytes but when i try to read get 114940 bytes. Anyone has idea?

I focused same topic that you are said about. I am using spymemcached client to write the cache and nginx read wrong data. After your reply i tried to write with whalin memcached client and tried to read both spymemcached and nginx. Neither nginx nor spymemcached can read data from cache. Does nginx have any configuration that i configure which memcached client nginx use? Or anyone know which memcached client can run with nginx properly?

More or less any memcached client can work properly with nginx, you just need to figure out how to write raw data into memcached from your client, i.e. without compression, serialization and so on. In case of Perl clients it’s more or less default behaviour for all modules I know (Cache::Memcached, Cache::Memcached::Fast) as long as you write scalars to memcached. No idea about Java.

Hi My problem has been solved. If i put any image to cache with java spymemcached client, nginx get broken images. After that i changed my java client to whalin memcached client. Now i am putting images with java whalin memcached client and i can get images with nginx properly. But here is a important trick. You have to set SanitizeKeys attribute in whalin memcached client to false.
