    • Field Detail

      • cachingForRetransmission

        protected boolean cachingForRetransmission
        This boolean is true if the request must be cached.

      • chunking

        protected final boolean chunking
        If we are going to be chunking, we won't flush till close which causes new chunks, small network packets, etc..

      • cachedStream

        protected org.apache.cxf.io.CacheAndWriteOutputStream cachedStream
        This field contains the output stream with which we cache the request. It maybe null if we are not caching.

        protected void makeTrustDecision()
                          throws IOException
        This call must take place before anything is written to the URLConnection. The URLConnection.connect() will be called in order to get the connection information. This method is invoked just after setURLRequestHeaders() from the WrappedOutputStream before it writes data to the URLConnection. If trust cannot be established the Trust Decider implemenation throws an IOException.
        Throws:
        IOException - This exception is thrown if trust cannot be established by the configured MessageTrustDecider.
