[SOLVED] Number/Hash sign in URL after submitting form

Here's my code:

Code:

#include <SPI.h>
#include <Ethernet.h>

// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192,168,1,20);

// Initialize the Ethernet server library
// with the IP address and port you want to use
// (port 80 is default for HTTP):
EthernetServer server(80);

const char* iContentLengthPtr;
const char* kContentLengthPrefix = "Content-Length: ";

typedef enum {
  eIdle,
  eStatusCodeRead,
  eReadingContentLength,
  eReadBody,
  eSkipToStartOfBody,
  eReadingBody,
  eReadFormElement
} tHttpState;

int laserPin = 9;

void setup() {

  // Open serial communications and wait for port to open:
  Serial.begin(9600);

  // start the Ethernet connection and the server:
  Ethernet.begin(mac, ip);
  server.begin();

  // initialize the digital pin as an output.
  pinMode(laserPin, OUTPUT);

}

void loop() {

  tHttpState iState = eStatusCodeRead;
  int iContentLength = 0;
  int iElementCount;

  iContentLengthPtr = kContentLengthPrefix;

  char e[2][16];
  char *element;

  // listen for incoming clients
  EthernetClient client = server.available();
  if (client) {

   // client.available() returns the number of bytes the client has yet to return
   // This number decreases everytime we do a client.read()
   while (client.available() > 0) {

   char c = client.read();
   Serial.write(c);

   switch(iState) {

   case eStatusCodeRead:
   if (*iContentLengthPtr == c) {
   iContentLengthPtr++;
   if (*iContentLengthPtr == '\0') {
   iState = eReadingContentLength;
   }
   } else {
   iContentLengthPtr = kContentLengthPrefix;
   }
   break;

   case eReadingContentLength:
   if (isdigit(c)) {
   iContentLength = iContentLength*10 + (c - '0');
   } else {
   iState = eSkipToStartOfBody;
   }
   break;

   case eSkipToStartOfBody:
   if (client.available() <= iContentLength) {
   iState = eReadingBody;
   iElementCount = 0;
   }
   break;

   case eReadingBody:
   if (c == '=') {
   iElementCount++;
   memset(e[iElementCount], 0, 16);
   element = e[iElementCount];
   iState = eReadFormElement;
   }
   break;

   case eReadFormElement:
   if (c != '&') {
   *element++ = c;
   } else {
   iState = eReadingBody;
   }
   break;

   default:
   break;
   }

   }

   if (strcmp(e[1],"on") == 0) {
   digitalWrite(laserPin, HIGH);
   } else {
   digitalWrite(laserPin, LOW);
   }

   client.println("HTTP/1.1 200 OK");
   client.println("Content-Type: text/html charset=utf-8");
   client.println("Connnection: close");
   client.println();
   client.println("<!DOCTYPE html>");
   client.println("<html>");
   client.println("<head>");

   client.println("<script src=\"http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js\"></script>");
   client.println("<title>Martien's Arduino</title>");
   client.println("</head>");
   client.println("<body>");
   client.println("<div data-role=\"page\">");
   client.println("<div data-role=\"header\">");
   client.println("<h1>Martien</h1>");
   client.println("</div>");
   client.println("<div data-role=\"content\">");
   client.println("<form method=post action=\"http://arduino.martin.us.com/\">");
   client.println("<fieldset data-role=\"fieldcontain\">");
   client.println("<label for=\"flip-1\">Laser</label>");
   client.println("<select name=\"flip-1\" id=\"flip-1\" data-role=\"slider\" data-mini=\"true\">");
   client.write("<option value=\"off\"");
   if(!bitRead(PORTB, 1)) client.write(" selected");
   client.println(">Off</option>");
   client.write("<option value=\"on\"");
   if(bitRead(PORTB, 1)) client.write(" selected");
   client.println(">On</option>");

  }
}
