I found the answer by own. I am posting this because, in future people who in same situation can refer this.

1. Its as normal, You need to have a special character like "*" (a delimiter), from which there gonna be some important data flowing through.

     char z = '*';
      int s=0;
   
   
     void setup()
      { 
       // usual initialization  
      } 
   
    void loop()
     {
     if (client.available())  
      {
       char c = client.read();
       // Serial.print(c);
       if (z == c)
         {
            s=1;
         }
   
      if(s == 1)
         {
          int i=0;
          k[i] = c;
          i=i+1;
        // Serial.print(k);
         }
   
     place +=k;
   
    Serial.print(place);
   
       }
   
     .......
        }
   

Here is what I found:

You need to have a special character like "*" (a delimiter), from which important data will flow through.

char z = '*';
int s=0;

void setup()
{ 
  // usual initialization  
} 

void loop()
{
  if (client.available())  
  {
    char c = client.read();
    // Serial.print(c);
    if (z == c)
    {
      s=1;
    }

  if(s == 1)
  {
    int i=0;
    k[i] = c;
    i=i+1;
    // Serial.print(k);
  }

  place +=k;

  Serial.print(place);

  }
