Introduction

Setting up IoT devices as ordinary HTTP accessible servers, both over IPv4 and IPv6 exposes those devices to the whole internet unless you take special care of the traffic in a router or firewall.

with the usage of the | XEP-0332 HTTP over XMPP extension it is possible to provide a protected pathway to the device.

The XMPP protocol does not have the same problems as HTTP in these regards. It's a peer-to-peer like protocol naturally allowing communication with applications and devices behind firewalls. It also includes advanced user authentication and authorization which makes it easier to make sure unauthorized access to private content is prevented.

Furthermore, with the advent of semantic web technologies and its use in web 3.0 and Internet of Things applications, such applications move even more rapidly into the private spheres of the users, where security and privacy is of paramount importance, it is necessary to use more secure transport protocols than HTTP over TCP.

There are examples of other protocols transported over XMPP | XEP-0072 SOAP Over XMPP

There are many different types of HTTP-based communication that could be transported

• Web Content like pages, images, files, etc.
• Web Forms.
• Web Services (SOAP, REST, etc.)
• Semantic Web Resources (RDF, Turtle, etc.)
• Federated SPARQL queries (SQL-type query language for the semantic web, or web 3.0)
• Streamed multi-media content in UPnP and DLNA networks.

But instead of trying to figure out all possible things transportable over HTTP and make them transportable over XMPP, this document ignores the type of content transported, and instead focuses on encoding and decoding the original HTTP requests and responses, building an HTTP tunnel over an existing XMPP connection.

It would enable existing applications to work seamlessly over XMPP if browsers and web services supported this extension (like displaying your home control application on your phone when you are at work), without the need to update the myriad of existing applications. It would also permit federated SPARQL queries in personal networks with the added benefit of being able to control who can talk to who (or what can talk to what) through established friendship relationships.

This making it possible to move existing applications (web applications, web services, semantic applications, etc. hosted on the web) and move them into new settings (for instance hosting it at home) and be able to reuse them without having to change them or opening ports in firewalls. An example would be to access your thermostat (that has a built in web page) from your office.
