For legacy reasons, Fiddler logs the message "HTTPSLint> Warning: ClientHello record was {0} bytes long. Some servers have problems with ClientHello's greater than 255 bytes"
This message should be removed because at this point, effectively ALL clienthellos are over 500 bytes and basically all servers are okay with it.
(This message was only relevant around 2014 or so when longer clienthellos started becoming common)
