Testing the HTTP server

If you included the HTTP server in TCP/IP Stack code image using any web browser you can connect to the server using the board IP address or optionally if you included the NetBIOS Name Service module using the assigned hostname with an URL such as http://PICNET1/.

The browser window will show a screen similar to the image shown in Figure 1 below

Notice that the home page includes AJAX code to continuously update the status of several variables shown on the page such as the IP packet counters or the LEDs status. The sample HTTP documents includes a variant of the home page without the AJAX code but including the variables, the whole page will reload automatically every few seconds and the variables will show the updated value.
