    • HttpVersion

      public HttpVersion(java.lang.String text, boolean keepAliveDefault)
      Creates a new HTTP version with the specified version string. You will not need to create a new instance unless you are implementing a protocol derived from HTTP, such as RTSP and ICAP.
      Parameters:
      keepAliveDefault - true if and only if the connection is kept alive unless the "Connection" header is set to "close" explicitly.

    • HttpVersion

      public HttpVersion(java.lang.String protocolName, int majorVersion, int minorVersion, boolean keepAliveDefault)
      Creates a new HTTP version with the specified protocol name and version numbers. You will not need to create a new instance unless you are implementing a protocol derived from HTTP, such as RTSP and ICAP
      Parameters:
      keepAliveDefault - true if and only if the connection is kept alive unless the "Connection" header is set to "close" explicitly.
