Basically this is my code. It works on Win7/2008 for POST as well as for
GET/HEAD (which return just 403) but under XPSP3 GET/HEAD still works from
browser but the POST fails. Just returns nothing--as if it is aborted. I do
not have debugger on the XP machine but one thing very strange is it works
when the engine (server) is in debug exe but not when it is as service. The
service is optimized code. So I am clueless right now.

void __fastcall AdminServer::HTTPServerPostDocument(TObject *Sender, TObject
*Client, Overbyteicshttpsrv::THttpGetFlag &Flags)
{
 THttpConnection *httpClient = (THttpConnection*)Client;
 AdminServerConnectionData *connectionData =
(AdminServerConnectionData*)(void*)httpClient->Tag;
 connectionData->docSize = 0;
 forceRestart = false;
 if(httpClient->RequestContentLength <= (4 * 1024 * 1024))
  Flags = hgAcceptData;
}
//---------------------------------------------------------------------------
void __fastcall AdminServer::HTTPServerPostedData(TObject *Sender, TObject
*Client, WORD ErrCode)
{
 THttpConnection *httpClient = (THttpConnection*)Client;
 AdminServerConnectionData *connectionData =
(AdminServerConnectionData*)(void*)httpClient->Tag;
 if(ErrCode)
 {
  httpClient->PostedDataReceived();
  httpClient->Abort();
 }
 else
 {
  int Len = httpClient->Receive((void*)connectionData->buffer, 8192);
  if(Len <= 0)
   return;
  connectionData->stream->Write((void*)connectionData->buffer, Len);
  connectionData->docSize += Len;

  if(connectionData->docSize >= httpClient->RequestContentLength)
  {
   httpClient->PostedDataReceived();
   connectionData->stream->Seek(0, 0);
   TMemoryStream *responseXML = processRequest(connectionData->stream,
httpClient);
   Overbyteicshttpsrv::THttpGetFlag Flags;
   httpClient->DocStream = responseXML;
   httpClient->SendStream();
  }
 }
}
//---------------------------------------------------------------------------

Best Regards,
