A minor change on Android API Level 2.3.3

gistfile1.java

HttpURLConnection httpConnection = (HttpURLConnection) url.openConnection();
String sHeader = httpConnection.getHeaderFieldKey(i);

if (sHeader.equals("content-length")) {
    //Unpredictable
    //Under the same server setup, the API level before 2.3.3 will return true.
    //But not this one
}


if (sHeader.equalsIgnoreCase("content-length")) {
    //True
    //It seems that in 2.3.3, all header field key are case sensitive.
}

//Summary: Always use equalsIgnoreCase, if letter case is not needed.
