			<description><![CDATA[I’m trying to implement a simple caching layer for my API responses using Redis, but I’m running into a problem where stale data keeps getting served after an update. My current setup invalidates the key on a POST request, but it seems like race conditions might be causing old data to be rewritten. I’m not sure if my approach to cache invalidation is fundamentally flawed or if I just need a different locking strategy.]]></description>

I keep reading that it helps with encapsulation, but in my current project, adding a separate method for object creation just feels like extra boilerplate without a clear benefit.]]></description>
