Re: [twsocket] HttpCli TransferEncoding
I can't get the client working with it. httpCli.TransferEncoding is a readonly property. How can I set the transfer encoding to chunked and send seperate chunks ? From what I see there is no easy way to do it with the HttpCli, without overriding some methods or/and add your own PostChunked method. The existent TransferEncoding property is used only to handle responses. -- 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] HttpCli TransferEncoding
So it's currently impossible with THttpCli :-( I should at least be able to send substreams without ending the post request, but haven't found a way to do this yet.

Are you sure the HTTP allows chunked encoded POST requests and server commonly support it? I should at least be able to send substreams without ending the post request, but haven't found a way to do this yet. I wonder what you want to achieve? If you managed to keep one conection alive by sending an infinite data stream it won't ensure that the other connection, your work connection, won't be disconnected nevertheless. -- Arno Garrels Paul - Original Message - From: Arno Garrels arno.garr...@gmx.de To: ICS support mailing twsocket@elists.org Sent: Thursday, February 04, 2010 5:18 PM Subject: Re: [twsocket] HttpCli TransferEncoding Paul wrote: I can't get the client working with it. httpCli.TransferEncoding is a readonly property.

If you are on v7 I hope you noticed that the HTTP server component got a new timeout feature that disconnects clients even when they established Keep-Alive connections?

I use a modified version. I'm trying to send a never ending stream in chunks. Each chunk contains the length of the substream, so I should be able decode it on the fly on the server. At least, that's what I'm trying to do. If I do this the normal way, some messages are received too late, even with connection keep-alive. Google is currently working on a new protocol (SPDY) to overcome this problem. With Http(s), you have to send a new request each time for each message and there is a huge delay if multiple proxies are in between.

Not exactly. Any device analysing the content has to decode chunks. I still don't get it right then. What is the problem with sending a large file and pause the transfer for a few seconds in between ?
