The USNET® Web Server offers Web access to real-time embedded applications. The USNET Web Server is a full-featured HTTP server optimized to run in 16 and 32-bit embedded environments. The USNET Web Server allows creation of compact and powerful applications because no file system, operating system, or dynamic memory is required. In a typical Web enabled application running an HTTP server on a 16-bit target (e.g. x86), the USNET protocol stack together with the USNET Web Server require less than 45 Kbytes of code space. The USNET Web Server may also be used in a multitasking environment such as U S Software's SuperTask!
General Features:
• HTTP 1.0 protocol and HTTP 1.1 features adapted for the embedded environment
• Processor independent
• RTOS independent
• Stack independent: The Web Server uses a BSD socket API to interface to a TCP/IP stack; use our USNET TCP/IP stack, or another of your choice
• Supports HTML 3.x and 4.x, Java applets, and all image formats
• CGI functions with persistent environment variables: Web CGI programs become CGI functions in the embedded world
• Dynamic page content with META commands and server-side includes
• Dynamic web page upload -- add new web pages to your web server while your application is running with no requirement for a file system or dynamic memory.
• User authentication: both Basic and Digest (MD5) Authentication methods
Three modes of operation:
• Interrupt: The Web Server responds to a user interrupt with an action. Best for small applications and quick control functions
• Polled: A function polls for user-defined criteria; the Web Server responds when needed for an action. Best for systems without an operating system
• Multithreaded: The Web Server is run as a task in a multitasking system. The Web Server can be a single-threaded task which handles one request at a time or each new request may create new tasks to handle simultaneous requests. Best for large applications requiring a multithreaded operating system
Ease of development:
• Design and prototype your web application using standard web design tools
• Process pages through our preprocessor to generate embedded web pages
