Method Detail

• getConnectionId

  java.lang.String getConnectionId()

  Obtain a unique (within the lifetime of the JVM) identifier string for the network connection to the JVM that is being used for the ServletRequest from which this ServletConnection was obtained.

  There is no defined format for this string. The format is implementation dependent.

  Returns:

  A unique identifier for the network connection

• getProtocol

  java.lang.String getProtocol()

  Obtain the name of the protocol as presented to the server after the removal, if present, of any TLS or similar encryption. This may not be the same as the protocol seen by the application. For example, a reverse proxy may present AJP whereas the application will see HTTP 1.1.

  If the protocol has an entry in the IANA registry for ALPN names then the identification sequence, in string form, must be returned. Registered identification sequences MUST only be used for the associated protocol. Return values for other protocols are implementation dependent. Unknown protocols should return the string "unknown".

  Returns:

  The name of the protocol presented to the server after decryption of TLS, or similar encryption, if any.

• getProtocolConnectionId

  java.lang.String getProtocolConnectionId()

  Obtain the connection identifier for the network connection to the server that is being used for the ServletRequest from which this ServletConnection was obtained as defined by the protocol in use. Note that some protocols do not define such an identifier.

  Examples of protocol provided connection identifiers include:

  HTTP 1.x

  None, so the empty string should be returned

  HTTP 2

  None, so the empty string should be returned

  HTTP 3

  The QUIC connection ID

  AJP

  None, so the empty string should be returned

  Returns:

  The connection identifier if one is defined, otherwise an empty string

• isSecure

  boolean isSecure()

  Determine whether or not the incoming network connection to the server used encryption or not. Note that where a reverse proxy is used, the application may have a different view as to whether encryption is being used due to the use of headers like X-Forwarded-Proto.

  Returns:

  true if the incoming network connection used encryption, otherwise false
