Ethernet Shield - Html Button - without use Servo.h Library

yes the led are necessary turned on based on what are arrive or send via virtual wire inside my program I've already the did the cicle for read the buffer and then based on the buffer i compare if what is arrived is for the devices or not ... so due the fact I need htlm page because I want assign my message to the variable pushing button from the web page ... for example

I push button and when I do it do the following

const char *msg = "hello";

digitalWrite(13, true); // Flash a light to show transmitting
vw_send((uint8_t *)msg, strlen(msg));
vw_wait_tx(); // Wait until the who

I've said don't use servo.h because the unique example that i see was the example did from zookmat where there was a servo.h ...

but for start for me could be fine also just a simple button ... from a web page ...

if need additional information please let me know thanks
