Right :-(
I will do it next week-end.

Hi Arno,
I downloaded version from main Overbyte site, link is
javascript:top.StartDownload('eng',
'arch/OverbyteIcsV7_Alpha1.zip');
Francois did not update his website for a long time, I must
admit that this is confusing, I pray multiple times a week
to get ICS from the wiki link :)

Hi Angus,
Thanks for helps.
I tryed install (with correction of inc file for version Ver210) and
have no success, 179 warnings and 3 errors.
You obviously did not try to install latest version, instead get
current ICS from:

1. Is it posible to use V7 in production environment, how stable
it now. I plan use as udp client and server, and http client and
server.
I already use V7 in a production environment, for commercial
applications.
2. What about Delphi 2010?
There were no changes needed in ICS for D2010, except version
conditionals and new packages, there's no reason to believe it's
any less reliable than use with Delphi 7, 2007 and 2009.

Re: [twsocket] Package Count / Wireshark
i used wireshark to monitor activity on the port i m listening on.Protocol is TCP and the server was build with ICS TWSocketServer. Monitoring packages arrived, I see that one of the packages (505 byte) is divided into 3 packages. What i want to ask; is this the way tcp protocol transfers data over network, or package count is because of the method client uses to send data..? ... Can we make a package transfered in a whole (in size limitations) or tcp decides how to transfer data by itself? Using PutDataInSendBuffer or PutStringInSendBuffer you can place data in the send buffer without actualy trying to send it. This allows to place several (probably small) data chunk before the component attempt to send it. This prevent small packet to be sent. You can call Send(nil, 0) to force the component to begin to send data. If the buffer was not empty, PutDataInSendBuffer will just queue data to the buffer. This data will be sent in sequence. -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] Package Count / Wireshark
Hi You can try to modify the normal behavior of TCP by setting wsoTcpNoDelay in TWSocket.ComponentOptions. This can avoid some TCP small packets caching.

Re: [twsocket] Package Count / Wireshark
Hello! i used wireshark to monitor activity on the port i m listening on.Protocol is TCP and the server was build with ICS TWSocketServer. Monitoring packages arrived, I see that one of the packages (505 byte) is divided into 3 packages. What i want to ask; is this the way tcp protocol transfers data over network, or package count is because of the method client uses to send data..? Depends. Packet size is typically limited to ~1500 bytes, can go up to few kilobytes if jumbo frames are enabled. Regardless, depending of through what your data have come, they can be split into smaller packets (that's called packet fragmentation). Also, if sending side disables Nagle algorhitm (sets tcpNoDelay flag), data are sent immediately - one packet per one send call. If that flag is not set, data are sent only after filling up a packet or after a few miliseconds of pause between send's. Can we make a package transfered in a whole (in size limitations) or tcp decides how to transfer data by itself? Between sending and receiving side there may be a router or bridge that can't handle certain packet sizes. At this point your packets might be split into two or more. The reason i am in this case is not the package count, but the headers used to form a package which makes data count increase.. See above. Either don't disable Nagle algorithm or send in large chunks. As receiving side, you can't do anything to reduce packet count. (as a side note, in client-server request-response scenarios, packet count can be dramatically reduced by utilizing pipelining, that is - sending all requests in one go and then waiting for responses instead of sending single request, waiting for response, sending another request, ... and so on; for POP3/NNTP protocol you usually can fit all your RETR/ARTICLE requests in just one outgoing packet). -- Piotr Dałek enigmati...@interia.pl -- Praca za granicą?
