Constructor Detail

DefaultHttpHeaders

public DefaultHttpHeaders()

DefaultHttpHeaders

public DefaultHttpHeaders(boolean validate)

Warning! Setting validate to false will mean that Netty won't validate & protect against user-supplied header values that are malicious. This can leave your server implementation vulnerable to CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting') . When disabling this validation, it is the responsibility of the caller to ensure that the values supplied do not contain a non-url-escaped carriage return (CR) and/or line feed (LF) characters.

Parameters:

validate - Should Netty validate Header values to ensure they aren't malicious.
