CustomColumns

Click Rules > Customize Rules and add the following code within the Handlers class to add a column that shows an MD5 hash of the response body:

public static BindUIColumn("MD5", 60)
 function FillMD5Column(oS: Session) { 
    if ((oS.responseBodyBytes == null) || (oS.responseBodyBytes.Length < 1))
   {
      return "No body";
   }

    var md5Hasher: System.Security.Cryptography.MD5 = System.Security.Cryptography.MD5.Create();
    var arrHash: byte[] = md5Hasher.ComputeHash(oS.responseBodyBytes);

    return BitConverter.ToString(arrHash);
 }
