Abstract: To design and research of an Embedded Thin Web Server in the environment of low-end microcontroller,streamlining the TCP/IP protocol stack,particularly,puting forward an accelerated open mechanism for TCP streamli-ning to avoid a three-way handshake process and has improved the technology of CGI.Using the Javascript to make part of the work of the serve shifted to the client to process,using XMLHttpRequest inplements Asynchronous communication between the server and the browser,so the performance of the server can be improvedt effectively.Through the test of performance shows that the server can meet the requirements of the embedded environment and this embedded Web server has a high practical value in the low-end platforms.
