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.

Regards
