Ethernet Shield with index.htm SDcard.

Viva, I managed to solve my problem.
Now only one point missing out ... I can not give and ask for help solving.

The code that is working and this:

Code: [Select]

Include <Ethernet.h>

Include <SPI.h>

/ *
Simple Ethernet Test

Arduino server outputs simple text to browser

The circuit:

  • Arduino Duemilanove
  • Arduino Ethernet shield
  • Basic FTDI 5V breakout
  • LED connected to digital pin 4 and GND via resistor

what is happening is this:
how do I access my shield through the browser
it goes OK, and do what you have to do is:

Show a field where you put the password and then do a submit button and proceed to the main page.

Ate there all right.

What is bad is if I close the browser and return the ip of my shield in the browser, it does not already asking for the password but goes directly to the main page and I do not want it.

Thank you
