Gist is use of HTTP protocol which allows you to define host in your request on virtual host server. Here are the possible headers.

http://en.wikipedia.org/wiki/List_of_HTTP_headers

You should also provide basic debugging info like “User-Agent” etc.

#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 };
byte ip[]             = { 192, 168,   6,  30 };

byte server[]         = { ***, ***, 168,  16 }; // Your VPS

// Initialize the Ethernet client library
// with the IP address and port of the server
// that you want to connect to (port 80 is default for HTTP):
Client client(server, 80);

String response = "";

void setup() {
  Ethernet.begin(mac, ip);
  Serial.begin(9600);
  // Give the Ethernet shield a second to initialize
  delay(1000);
  Serial.println("Connecting...");
}

void loop() {
  if (!client.available() && client.connect()) {
    Serial.println("-- Connected");
    // Make a HTTP request:
    client.println("GET /bot HTTP/1.0");
    client.println("Host: example.com");
    client.println("User-Agent: Arduino/Shishir (mail.mastermind [at] gmail.com)");
    client.println();
  }
  if (client.available()) {
    char c = client.read();
    response.concat(c);
  }
  if(!client.connected()){
    process(response);
    //Serial.print(response);
  }
  if (!client.connected() && reset == 1) {
    Serial.println("disconnecting.");
    client.stop();
    response = "";
    delay(1000*10);
  }
}
void process(String response) {
  Serial.println(response);
}

I did all the things I could do.

• Reset Arduino.
• Reset Ethernet Shield.
• Change Ethernet cat5 cable to shorter one.
• Change Router setting.
• Change MAC address in program.
• Change last 2 octets of IP 192,168,6,xxx to 192,168,1,xxx.
• At last Google about this issue.

Point to be noted I was able to run WebServer sketch and it was flawless. So I was sure shield is good.

With a quick google found this thread on http://www.arduino.cc.

Some one said that don’t connect google . Bingo. Its Google.

Fcuk that.  But WebClient too works flawlessly.

Step 1. Install ctags in your system. For mac

$ sudo port install ctags

Step 2. Create A tag file

$ cd /Users/username/Workspace/rails-project
$ ctags -e -a --Ruby-kinds=+f -o TAGS -R app/ lib/ config/

It is best to add this in crontab for this around 11:30am

Step 3.1 emacs

M-. Follow a tag
M-* Jump back to source.

Step 3.2 vim
just add this in your ~/.vimrc

set tags=TAGS;/

Once this is done you can navigate to source of tag by using.

C-] - go to definition
C-T - Jump back from the definition.
C-W C-] - Open the definition in a horizontal split

Hope you will be able to use this awesome feature.
C is ctrl
M is Meta/Alt/Ecs

Bigger Bad news is that age old trick will NOT work here, we can not solve this simply by adding

Best way in my opinion is to reject download count based on the user agent. Which is Googlebot in case of Google Crawler.

find long answer here.

Jeba(graydot), Pranav(silent_horror), Jai(*thunder), Tushar(zombi), Kanav(Ka_boom) and I(cpt) are in one team and Prafulla(Element), Sahil(Engassa), Arpit(cctv), Shirsendu(Toy_da_virus) and Ankur(danger) are in the other one. Kapil(anachronox) will use auto join.

Suggest me names guys.
