Class HTTPResponseOutputStream

  • All Implemented Interfaces:
    Closeable, Flushable, AutoCloseable

    class HTTPResponseOutputStream
    extends FilterOutputStream
    This does the transparent gzip decompression on the client side. Extended in I2PTunnelHTTPServer to do the compression on the server side. Simple stream for delivering an HTTP response to the client, trivially filtered to make sure "Connection: close" is always in the response. Perhaps add transparent handling of the Content-Encoding: x-i2p-gzip, adjusting the headers to say Content-Encoding: identity? Content-Encoding: gzip is trivial as well, but Transfer-Encoding: chunked makes it more work than is worthwhile at the moment.

      • HTTPResponseOutputStream

        public HTTPResponseOutputStream​(OutputStream raw)
      • HTTPResponseOutputStream

        public HTTPResponseOutputStream​(OutputStream raw,
                                        boolean allowKeepAliveIn,
                                        boolean allowKeepAliveOut,
                                        boolean isHead,
                                        LimitOutputStream.DoneCallback cb)
        Optionally keep sockets alive and call callback when we're done.
        Parameters:
        allowKeepAliveIn - We may, but are not required to, keep the input socket alive. This is the server on the server side and I2P on the client side.
        allowKeepAliveOut - We may, but are not required to, keep the output socket alive. This is I2P on the server side and the browser on the client side.
        isHead - is this a response to a HEAD, and thus no data is expected (RFC 2616 sec. 4.4)
        cb - non-null if allowKeepAlive is true
        Since:
        0.9.62

      • getKeepAliveIn

        public boolean getKeepAliveIn()
        Should we keep the input stream alive when done?
        Returns:
        false before the headers are written
        Since:
        0.9.62
      • getKeepAliveOut

        public boolean getKeepAliveOut()
        Should we keep the output stream alive when done? Only supported for the browser socket side. I2P socket on server side not supported yet.
        Returns:
        false before the headers are written
        Since:
        0.9.62
      • filterResponseLine

        protected String filterResponseLine​(String line)
        Possibly tweak that first HTTP response line (HTTP/1.0 200 OK, etc). Overridden on server side.
      • shouldCompress

        protected boolean shouldCompress()
