[twsocket] ICS Sockets for sending receiving files
Hi I want to use ICS Sockets to send/receive files but can't see any example. All examples are for Text.After working on developing my application with FTP and getting to production stage I get to know that AntiViruses hate FTP and they just throw my application out. Therefore I am looking at Basic Sockets for sending files.

[twsocket] Socket States
Hi, Can I seggregate the Socket states such that 1)if all is well and workable then we are in either wsConnected or wsListening state. 2)After Close or Error etc and after timeout elapses we will go into wsClosed 3) All below states are temporary and will in a minute or so go into the two above mentioned states ? wsInvalidState,wsOpened,wsBound,wsConnecting, wsSocksConnected, ,wsAccepting, I am asking this as I do not want to re-attempt connecting during the intermediate states.

[twsocket] TWSocket Timeout Property ?
Hi, If I try to connect my TWSocket and there is no socket listening on the other end then the TWSocket's state goes into wsConnecting for a long time. I want to reduce that Timeout. Which property should I use ?

Presumably the latest V8.50 version from August? Is the server running on Windows Server OS, or a client windows? You say 'intensive', what does that mean? I've tested hundreds of simultaneous FTP sessions, but it was a long time ago.

[twsocket] Role of Error in Socket OnConnectedEvents
Hi, In the ICS Socket components's OnSessionConnected / OnClientConnect events you are passing Error parameter. When will this get a value ?If the OnConnected events are triggered does it mean connection is active or is it only if Error=0 ?

Re: [twsocket] Aborting a File Transfer from FtpServer
Hi, Just wanted to know if there is a ready made option to stop a transfer midway. Now that you have cleared my doubts I will program accordingly.

The FTP server is usually non-interactive, it would not consider aborting a transfer part way through. There are no protocol commands for reverse ABORT, or indeed to confirm a transfer has successfully completed or been stopped part way through, the data connection is simply closed by the server. The server can decide not to start a transfer and return an error code instead, perhaps that is what you mean by abort? If the server PC was closing down, all sockets would simply close.

You will find the TMagFtp component works very closely with the ICS web server, for bulk file uploads and downloads, with all the automated file checking and resumed uploads handled automatically, and extensively tested for 12 years. In particular they use special commands to index sub-directories, so a single FTP call will return a list of thousands of sub-directories, whereas a normal FTP server would need to list each one separately with thousands of commands. Suggest you test the compiled xferdemo3.exe demo against the ICS FTP server sample. It will save you a lot of development effort.

Partial uploads were common in the days of dial-up internet and now with flakey mobile connections. But it's the client's job to check the server has received the file correctly, with CRC, file size, etc. Don't delete a partially uploaded file, the client may want to resume the upload, which TMagFtp handles.

Suggest you look at the source code for TMagFtp at: https://www.magsys.co.uk/delphi/magxfer.asp which does all this already. Generally, you check the correct sized file has arrived, and perhaps run a CRC or MD5 check on it, to check it's not corrupted before renaming it to the final name, if the server supports such commands.

I've tested 2,000 simultaneous TCP/IP sessions in a single thread, on Windows 10. The main limitation I found was connection time, particularly with SSL which has a heavy overhead opening each new session. So there is a restriction to how many new sessions can be opened each second, I think it was about 100 with SSL TLS/1.2, although that might improve with the next generation TLS/1,3 which is more efficient.
