Good Day!

Does anybody have any experience using the CInternetSession::SetOption() to
set the timeout for CHttpFile::Read()? Or is there any other method to do
the job?

I have tried the CInternetSession::SetOption() as follow (it did not work):

CInternetSession session("Http");
session.SetOption( INTERNET_OPTION_DATA_RECEIVE_TIMEOUT, 10000);
CHttpConnection pServer = session.GetHttpConnection( ServerName, nPort);

CHttpFile File = pServer.OpenRequest(CHttpConnection::HTTP_VERB_POST, file);

try
{
File.SendRequest(sHeader,(LPVOID)sBody, sBody.GetLength());
}
catch(CInternetException *e )
{
..............
e->Delete();
return FALSE;
}

UINT nRead;
DWORD dwRet;
File.QueryInfoStatusCode(dwRet);

if(dwRet == HTTP_STATUS_OK)
{
try
{
while(nRead=pFile.Read(szBuf, 100)){
............
}
}
catch(CInternetException *e)
{
............
e->Delete();
}

The problem is this:
If the Web Server returned some data, then crashed or just sat idle forever
without returning anything . It should time out after 10 seconds as I have
set in the CInternetSession::SetOption(), but it failed to do that. It
also sat idle until it finally received an Internet Exception at
approximately 15 minutes later.

Where did you find that info? I think that constant it is no longer
supported starting from IE 5.0

Yes, connect timeout is fixed but receive timeout is removed.
INTERNET_OPTION_RECEIVE_TIMEOUT no longer works in Internet Explorer 5.0.
For more information, see the following article in the Microsoft Knowledge
Base: Q224318
Note that Q224318 is applicable to IE 5, 5.5 etc.
