Memcached with Windows and .NET

How do I tell Spring cache not to cache null value in @Cacheable annotation
Hooray, as of Spring 3.2 the framework allows for this using Spring SPEL and unless.

Unlike condition(), this expression is evaluated after the method has been called and can therefore refer to the … Read more
If redis is already a part of the stack, why is Memcached still used alongside Redis?
The main reason I see today as an use-case for memcached over Redis is the superior memory efficiency you should be able to get with plain HTML fragments caching (or similar applications).

Redis and Memcache or just Redis?
Assuming that migrating from memcached to redis for the caching you already do is easy enough, I’d go with redis only to keep things simple. In redis persistence is optional, so you can use it much like memcached if that is what you want. You may even find that making your cache persistent is useful … Read more
