Hello,

if an url is a subdomain it is recognised by the browser.

e.g.

http://www.subdomain.com

is redirected to:

http://www.domain.com/subdomain.index.htm

Are there functions to query the domain if a subdomain
is opened with:

BOOL Bsuccess = TRUE;
CInternetSession Isession;
CHttpFile* pFile = NULL;
try
{
pFile = (CHttpFile*)Isession.OpenURL("http://www.subdomain.com");
}
catch(CInternetException * e)
{
Bsuccess = FALSE;

*****
you are missing
e->Delete();
otherwise the exception object would not be deleted.
*****

}
catch(CFileException pEx)

*****
catch(CFileException* pEx)
*****

{
Bsuccess = FALSE;

*****
same here:
e->Delete()
*****

}

DWORD dwStatusCode;
if(Bsuccess == TRUE)

*****
Bsuccess is already a BOOL, and "if" takes a bool, so write this as
if (Bsuccess)
In fact, explictly comparing to TRUE will work in this special case but is WRONG
in most cases. "if" tests if the value is "not 0", so if BSuccess once happens
to be 2 or some value other that 0 or 1 it would still be considered true but
your "if (Bsuccess == TRUE) will do the wrong thing.

{
pFile -> QueryInfoStatusCode(dwStatusCode);
}

//dwStatusCode: 200 domain: OK

//dwStatusCode: 400 sub domain: error

Thanks for any clue!
