Abstract: In dynamic embedded Webserver，cgi program is adopted to serve the required workflow.However，the performance of embedded system is limited.To reduce the load of Webserver，this paper makes cgi and javascript collaboratively work to process the embedded webapplication.Cgi processes the parameters submitted by post command on client PC and appends the results to the end of html page，Javascript embedded in html page parses and displays the results on the right place.The paper also designs a method that detaches cgi，application program and driver，cgi can indirectly send parameter to driver by exchanging the parameter with application through shell environment.In this way，cgi and application can be designed and debugged independently.
