Chapter 4. Introduction to the Simple Content Storage
Protocol (SCSP)
The mechanism that applications use to communicate with DX Storage is a simple, text-based
protocol based on the HyperText Transfer Protocol (HTTP). Referred to as the Simple Content
Storage Protocol, or SCSP, its methods and syntax are a proper subset of the HTTP/1.1 standard.
Although many of the optional parts of HTTP/1.1 are not implemented in SCSP (which is why the
protocol is referred to as Simple), all required components of the protocol are implemented as
well as several of the common methods. Moreover, DX Storage assumes communication with an
HTTP/1.1 compliant client application.
In DX Storage version 5.0 for the first time, SCSP supports authentication and authorization on all
SCSP operations. For details, see
This chapter provides an overview of the most important parts of SCSP and how they map to HTTP.
For details on the semantics and other nuances of HTTP, see the Hypertext Transfer Protocol –
HTTP/1.1
specification. Developers wishing to write a native integration to DX Storage SCSP should
also refer to the DX Storage Software Development Kit (SDK) Overview for information on the API-
level implementation of the SCSP protocol, including complete source implementations of that API
in several common languages (currently Java, Python, C++, and C#).
