String stringOne = "Content-Type: text/html";
Serial.println(stringOne);

// substring(index) looks for the substring from the index position to the end:
if (stringOne.substring(19) == "html") {
Serial.println("It's an html file");
}
// you can also look for a substring in the middle of a string:
if (stringOne.substring(14,18) == "text") {
Serial.println("It's a text-based file");
}
// do nothing while true:
while(true);
