i have simple question to you... i want to make a simple Web Server with precessing. like this:

1. //zoomkat 5-24-10
   // http://www.arduino.cc/en/Tutorial/TextString for WString.h
   
   #include <WString.h>
   #include <Ethernet.h>
   
   byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; //physical mac address
   byte ip[] = { 192, 168, 1, 102 }; // ip in lan
   byte gateway[] = { 192, 168, 1, 1 }; // internet access via router
   byte subnet[] = { 255, 255, 255, 0 }; //subnet mask
   Server server(84); //server port
   
   String readString = String(100); //string for fetching data from address
   
   ///////////////////////
    String teststring = String(100);
    String finalstring = String(100);
    String flag = String(2);
    int ind1 = 0;
    int ind2 = 0;
    int pos = 0;
    //////////////////////
   
   void setup(){
   
   //start Ethernet
   Ethernet.begin(mac, ip, gateway, subnet);
   server.begin();
   
   //enable serial data print 
   Serial.begin(9600); }
   
   void loop(){
   // Create a client connection
   Client client = server.available();
   if (client) {
   while (client.connected()) {
   if (client.available()) {
   char c = client.read();
   
   //read char by char HTTP request
   if (readString.length() < 100) {
   
   //store characters to string 
   readString.append(c); 
   } 
   
   //if HTTP request has ended
   if (c == '\n') {
   
   ///////////////
   //Serial.println(readString);
   //readString looks like "GET /?-0p1555-1p500t1000 HTTP/1.1"
   
     if(readString.contains("-")) { //test for servo control sring
     readString.replace('-', '#');
     pos = readString.length(); //capture string length
     //find start of servo command string (#)
     ind1 = readString.indexOf('#');
     //capture front part of command string
     teststring = readString.substring(ind1, pos);
     //locate the end of the command string
     ind2 = teststring.indexOf(' ');
     //capturing the servo command string from readString
     finalstring = readString.substring(ind1, ind2+ind1);
     //print "finalstring" to com port;
     Serial.println(finalstring); //print string with CR
       }
     ////////////////////////
     //GET /?Slidervalue0=1800&Submit=Sub+0 HTTP/1.1
     if(readString.contains("Slidervalue")) {
     ind1 = readString.indexOf('u');
     ind2 = readString.indexOf('&');
     finalstring = readString.substring(ind1+1, ind2);
     finalstring.replace('e', '#');
     finalstring.replace('=', 'p');
     Serial.println(finalstring);
     }
     ///////////////////
     
     //now output HTML data header
     client.println("HTTP/1.1 204 Zoomkat");
     client.println();
     client.println();
     delay(1);
     //stopping client
   client.stop();
   
   /////////////////////
   //clearing string for next read
   readString="";
   teststring="";
   finalstring="";
     
   }}}}} 

Thanks a lot...
