Embedded HTTP server

An embedded HTTP server is a component of a software system that implements the HTTP protocol. Examples of usage within an application might be:

There are a few advantages to using HTTP to perform the above:

  • HTTP is a well studied cross-platform protocol and there are mature implementations freely available.
  • HTTP is seldom blocked by firewalls and intranet routers.
  • HTTP clients (e.g. web browsers) are readily available with all modern computers.
  • There is a growing tendency of using embedded HTTP servers in applications that parallels the rising trends of home-networking and ubiquitous computing.

Typical requirements[edit]

Natural limitations of the platforms where an embedded HTTP server runs contribute to the list of the non-functional requirements of the embedded, or more precise, embeddable HTTP server. Some of these requirements:

For every specific project, requirements can vary significantly. For example, ROM and RAM footprints can be a very serious constraint and limit the choices of the system designer. C++ or JVM availability for the system can be another constraint. Frequently performance is an issue, because typical embedded systems run multiple simultaneous tasks and an HTTP server is only one of them and may be configured as a low priority task.
