HTTP Shared Storage

Simple shared storage for web applications. Especially useful in closed intranet environments.

• Multiple clients can share data by using REST protocol
• Optimistic locking mechanism to sync clients (using ETag)
• Arbitrary mime type (not only JSON) support
• Use long polling for immediate change notification
• Stores all data in memory (lost on restart), which can be improved in future releases

Sample Angular application using this as a backend: Planning Poker.
