[twsocket] UDP SendTo
Hello, I would like to send datagrams thru SendTo() instead of Send() in order to bypass copying data to TWSocket's send buffer. When I call SendTo() I have to handle possible errors by myself, but I do not understand exactely whether it's possible that the function returns a positive result smaller than Len. The online help says: If no error occurs, sendto returns the total number of bytes sent, which can be less than the number indicated by len. OK, but a little bit later: For message-oriented sockets, care must be taken not to exceed the maximum packet size of the underlying subnets, which can be obtained by using getsockopt to retrieve the value of socket option SO_MAX_MSG_SIZE. If the data is too long to pass atomically through the underlying protocol, the error WSAEMSGSIZE is returned and no data is transmitted. Does this mean that in UDP either any number of bytes is sent or WSAEMSGSIZE is returned? --- Arno Garrels [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
[twsocket] Mime Decode Demo
Hi all, I would like to add MIME decoding capability into my pop3 mail client. The overbyte web page mentions that there is a MimeDemo app that instructs how to use the TMimeDecode component. However I could not find C++ samples in the installed directory of ICS, only in Delphi. I am using BCB6 and do not have Delphi to play with. Are there any MIME demo in C++ available? Many thx.-- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] Mime Decode Demo
Hello Francois, I think we should build BCB projects with Pascal DFMs to cover such inquries because not all of the Delphi code is converted to C++ and this would be an intermediate solution. When I joined this mailing list in 1999, I did not know Delphi but only C/C++ but they are very similar and it is not much diffucult to learn.

[twsocket] HTTPS forward proxy server
Hello, I wonder how forward proxy servers other than BlueCoat.com (there was a discussion about them before) read the SSL'ed Host address to forward the request to that IP/Port. Is there a special RFC for HTTPS proxies?

Re: [twsocket] UDP SendTo
Hello, This UDP stuff is driving me nuts. Maximum outbound (send) size of a message returned by getsockopt as described below is 65507 bytes on my w2k box. Up to this size datagrams go over the wire. However if I SendTo a bigger datagram up to 65527 bytes then SendTo happily returns success even though nothing was sent! At a datagram size of 65528 bytes however the function fails with WSAGetLastError returning WSAEMSGSIZE as stated in the M$ documentation, is this normal? Also, when I set the IP_DONTFRAGMENT flag before sending a datagram that would have being fragmented otherwise SendTo also happily returns success even though no data was sent. --- Arno Garrels [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html Arno Garrels wrote: Hello, I would like to send datagrams thru SendTo() instead of Send() in order to bypass copying data to TWSocket's send buffer.

If you do not mean a SSL filtering proxy like BlueCoat the proxy just tunnels the SSL traffic, see GpHttpProxy made with ICS, and THttpCli. --- Arno Garrels [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html Best Regards, SubZero -- To unsubscribe or change your settings for TWSocket mailing list please goto http://www.elists.org/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] HTTPS forward proxy server
Yes I know BUT how does it know the destination IP/port of the web server if the GET http://www.micro$oft.com/index.php ( :) ) is encrypted??

It cannot know that, there is a method CONNECT. The HTTP CONNECT method is described in an IETF Internet-Draft written by Ari Luotonen http://www.web-cache.com/Writings/Internet-Drafts/draft-luotonen-web-proxy-tunneling-01.txt This draft probably is expired, search google for updates. Once a client is authenticated, any traffic is just tunneled like it is done in Wilfried's socketspy. A real proxy component is GpHttpProxy. --- Arno Garrels [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html Thanks for the answer, SZ - Original Message - From: Arno Garrels [EMAIL PROTECTED] To: ICS support mailing twsocket@elists.org Sent: Wednesday, August 23, 2006 4:19 PM Subject: Re: [twsocket] HTTPS forward proxy server Fastream Technologies wrote: Hello, I wonder how forward proxy servers other than BlueCoat.com (there was a discussion about them before) read the SSL'ed Host address to forward the request to that IP/Port.

[twsocket] Using a Cookie in Http(s)Tst
Hi all, in the HttpTst demo I navigate to www.google.com. The output message shows Cookie: PREF=ID=64cd0e5f00d7a853:TM=1156389632:LM=1156389632:S=a7g_61J9fju4o_-X; expires=Sun, 17-Jan-2038 19:14:07 GMT; path=/; domain=.google.de Set-Cookie: PREF=ID=64cd0e5f00d7a853:TM=1156389632:LM=1156389632:S=a7g_61J9fju4o_-X; expires=Sun, 17-Jan-2038 19:14:07 GMT; path=/; domain=.google.de But when I add a button to the form and check for SslHttpCli1.Cookie, it is empty. Am I missing something? What I want to do in the application is to change 1 value and use the cookie to save the setting permanently.
