The number of bytes occupied in the application's memory by the Java String object is probably not the same as the number of bytes occupied by the same string in the HTTP response. I could be wrong on some points below but I'm sure others will correct me if so (Paul?) As I understand it, a Java program such as CF always stores characters internally using UCS-2 encoding, i.e. 2 bytes per character. In addition, the String object will include 20 or 30 extra bytes for storing the length of the string etc. I believe that CF's default behaviour is to encode HTTP responses using UTF-8 encoding, i.e. 1 byte per character if you're only using ASCII characters, and of course the extra bytes used by the String object won't be there either. So let's say your string is "Rob". - In CF the Len() function gives you 3. - The size of the Java object - even if you could work it out, which is next to impossible in Java - would be 6 + the extra bytes, maybe 40 or more. - But in the HTTP response it would probably be 3. So, if I've understood your question correctly and it's the HTTP response you're interested in, just using Len() in CF will give you the best answer.
