Board index » delphi » Indy 10 and winsock error 10053

Hello,
I am trying to POST to a web service using Indy 10 over and SSL connection.
The process works fine for most requests, but when my data gets too large (5
MB or so) it suddenly throws a socket exception with the error code 10053.
The strange thing it that it does this on the third packet of data, not
somewhere in the middle as I'd expect. If I send a 3 MB block of data,
it passes the third packet just fine, in fact, it sends the entire request.
Does anyone have any pointers on how to go about tracking this down?
Thanks,
Don

Software caused connection abort.
An established connection was aborted by the software in your host machine,
possibly due to a data transmission timeout or protocol error.

It is in C++. I post here only because the traffic is better.
void Execute(TIdHTTP *http) {
if (svc.SubString(1, 5) == "https") {
// Need an SSL IOHandler
TIdSSLIOHandlerSocketOpenSSL *ioh = new
TIdSSLIOHandlerSocketOpenSSL(http);
ioh->Port = 443;
ioh->UseNagle = false;
} // if
if (FOnConnected) http->OnConnected = HTTPConnected;
if (FOnProgress) {
http->OnWorkBegin = HTTPWorkBegin;
http->OnWork = HTTPWork;
http->OnWorkEnd = HTTPWorkEnd;
} // if
std::auto_ptr<TMemoryStream>req(new TMemoryStream);
req->Write(rqXML.data(), rqXML.Length());
req->Position = 0;
// Add the SOAPAction HTTP Header to the Request
String hdr = "SOAPAction: \"" + fAction.Server + fAction.Name + "\"";
http->Request->CustomHeaders->Clear();
http->Request->CustomHeaders->Add(hdr);
http->Request->Accept = "text/xml";
http->Request->AcceptCharSet = "utf-8";
http->Request->ContentType = "text/xml";
// Do it
resultStream->Clear();
http->Post(svc, req.get(), resultStream);
}
Again, it works up to something less than 8MB. Itgets to the third packet,
sits for a long time (30 seconds or so) then up comes the exception.

it to the TIdHTTP at all.
Write() has a return value that indicates the number of bytes actually
written to the stream.
Rather than using TMemoryStream, how about TStringStream instead?
std::auto_ptr<TStringStream>req(new TStringStream(rqXML));
Then you are not making a second copy of the data at all.
fAction.Server + fAction.Name + "\";
