The LogicBoxes API is a full-control set of programming interfaces that allow you and your resellers to develop your own Website and control panels and integrate them into LogicBoxes OrderBox. Every function of LogicBoxes OrderBox is exposed via the OrderBox API. You can duplicate any or all of the functionality at your end by integrating into the API. The API comes with a specification, client side kits, sample forms, sample code, and complete documentation. Integrating with the API is a breeze. The API is based on SOAP/WSDL. Client side kits are available in PHP, Perl, ASP.NET, and Java. Additionally, since the protocol is standards-based, the API is truly platform independent. Monitoring systems prevent API abuse and any denial of service attacks on the API servers. The API is scalable and secure.
Pagekite is software to make servers on "localhost" visible to the wider Internet. It can be used by Web developers to show off their works in progress to clients or colleagues, embedded developers who need direct access to devices in the field, or as an alternative to dynamic DNS for individuals/hobbyists who would rather host their own content than rely on 3rd party hosting. It creates and maintains a tunnel between your server on localhost and a remote "front-end" (a reverse proxy). Only the front-end has to have a visible IP address; the server itself can reside on a heavily firewalled computer, a mobile device, or even an anonymous node on the Tor network.
The yaSSL Embedded Web Server is a fast, embeddable, and easy-to-configure Web server with a strong focus on portability and security.

With a footprint size of less than 100kB with SSL enabled (or 40kB without SSL) and a simple and clean API, the yaSSL Embedded Web Server was designed to fit perfectly into resource-constrained embedded environments. While maintaining a small size and fast speeds, the yaSSL Embedded Web Server offers a full feature set to give you the maximum amount of freedom and flexibility when developing your project.
