          <p>[httpd] httpd_response:send_chunk handles empty list and 
          empty binary - i.e. no chunk is sent, but it does 
	  not handle a list with an empty binary [&lt;&lt;&gt;&gt;]. 
	  This will be sent as an empty chunk - which in turn 
	  will be encoded by http_chunk to the same as a final 
	  chunk, which will make the http client believe that 
	  the end of the page is reached.</p>

	    [httpc] If a request times out (not connect timeout), the
	    handler process exited (normal) but neglected to inform
	    the manager process. For this reason, the manager did not
	    clean up the request table., resulting in a memory leak.
	    Also the manager did not create a monitor for the
	    handler, so in an unforseen handler crash, this could
	    also create a memory leak.</p>

	  <p>[httpc] - Memory leak plugged. 
            The profile manager never cleaned up in its handler database. 
            This meant that with each new request handler, another entry 
            was created that was never deleted. Eventually the request
            id counter (used as a key) would wrap, but the machine would 
            most likely run out of memory before that happened.</p>

		<p>The <c>erl_script_timeout</c> config option is ducumented

            host name when making a request to a server listening on a port 
            other than the HTTP default of 80. Currently, only the host

	  <p>[httpc|httpd] http_chunk data handling/passing improvement. </p> 
          <p>This is a modification to the http_chunk module to forward any 
            full chunk received, regardless of whether the size field for the 
            following chunk has been received yet.  This allows http_chunk to 
            be used in situations where a long term HTTP connection is used to 
            send periodic status updates as individual chunks.  Previously a 
            given chunk would not be forwarded to the client process until the 
            size for the next chunk had been read which rendered the module 
            difficult to use for the scenario described. </p>

	      <item>
		<p>Initial call between the httpc manager and request

		<p>When the manager starts a new request handler, 
                  this is no longer a synchronous operation. Previously, 
                  the new request handler made the connection to the 
                  server and issuing of the first request (the reason 
                  for starting it) in the gen_server init function. 
                  If the connection for some reason "took some time", 
                  the manager hanged, leaving all other activities by 
                  that manager also hanging. </p>

          <p>These functions is documented as working on directories, but 
            this is actually not according the standard. The LIST and NLST
            commands are specified to operate on a directory or other 
            group of files, or a file.</p>
          <p>Previously, an attempt was made to check if the listing
            returned by the server was actually an error message. This
            was done by changing remote directory (cd) into the 
            (assumed) "directory". This may work if Pathname was actually 
            a directory, but as this is not always the case, this test 
            does not work. Instead, we now return the actual server 
            result and leave the interpretation to the caller. </p>

            [tftp] If a callback (which performs the file access in
            the TFTP server) takes too long time (more than the
	    double TFTP timeout), the server will abort the
            connection and send an error reply to the client. This
	    implies that the server will release resources attached
            to the connection faster than before. The server simply
            assumes that the client has given up.</p>
          <p>
            [tftp] If the TFTP server receives yet another request
            from the same client (same host and port) while it
            already has an active connection to the client, it will
            simply ignore the new request if the request is equal
            with the first one (same filename and options). This
            implies that the (new) client will be served by the
            already ongoing connection on the server side. By not
            setting up yet another connection, in parallel with the
            ongoing one, the server will consumer lesser resources.</p>
          <p>
            [tftp] netascii mode is now supported when the
            client/server has native ascii support (Windows). The new
            optional parameter native_ascii in the tftp_binary and
            tftp_file callback modules can be used to override the
            default behavior.</p>
          <p>
            [tftp] Yet another callback module has been added in
            order to allow customized handling of error, warning and
            info messages. See the new configuration parameter,
            logger.</p>
          <p>
            [tftp] Yet another configuration parameter, max_retries,
            has been added in order to control the number of times a
            packet can be resent. The default is 5.</p>
          <p>
            [tftp] tftp:info/1 and tftp:change_config/2 can now be
            applied to all daemons or all servers in one command
            without bothering about their process identifiers.</p>

            [tftp] Blocks with too low block numbers are silently
            discarded. For example if a server receives block #5 when
            it expects block #7 it will discard the block without
            interrupting the file transfer. Too high block numbers
            does still imply an error. External TR HI96072.</p>

            and stopped i.e. it will not automatically be started as
            a temporary application as it did before. Although a
            practical feature when testing things in the shell it is
            not desirable that people take advantage of this and not
            start the Inets application in a correct way in their
            products. Added functions to the Inets API that call
            application:start/stop.</p>
