Hi,
I have following code for Adding cookie using ISAPI filter, if i try to set domain name i.e. give "domain =" word in cookie string it does not create cookie if i give other then "domain =" then it created cookie.

cookie1.Format("%s%s%s%s%s%s","Set-Cookie: ",m_configFileRead.m_sCookieName,"=",m_configFileRead.m_ResponseCookie,"; domain=localhost","; path=/",";\r\n");
BOOL val = pCtxt->AddResponseHeaders(cookie1.GetBuffer(), 0);
