Thanks for the links. I allready gone through the links and found solution. It should as follows.... HINTERNET hOpenHandle, hConnectHandle, hResourceHandle;WORD dwError, dwErrorCode; hOpenHandle = InternetOpen(NULL,INTERNET_OPEN_TYPE_PROXY, _T("192.168.9.10:8080"), NULL, INTERNET_FLAG_SECURE); // _T("192.168.9.10:8080") is proxy with port number DWORD dwServiceType = AFX_INET_SERVICE_HTTP; CString szServer, szObject; INTERNET_PORT nPort; AfxParseURL (strURL, dwServiceType, szServer, szObject, nPort); // strURL is any URL whose data to retrieve say http://www.google.com hConnectHandle = InternetConnect(hOpenHandle,szServer,INTERNET_INVALID_PORT_NUMBER, _T("test1"), _T("test"), INTERNET_SERVICE_HTTP, 0, 0); // _T("test1"), _T("test") is username and password for proxy at my server hResourceHandle = HttpOpenRequest(hConnectHandle, _T("GET"), szObject, NULL, NULL, NULL, INTERNET_FLAG_KEEP_CONNECTION, 0); resend: HttpSendRequest(hResourceHandle, NULL, 0, NULL, 0); DWORD dwStatus; DWORD dwStatusSize = sizeof(dwStatus); HttpQueryInfo(hResourceHandle, HTTP_QUERY_FLAG_NUMBER | HTTP_QUERY_STATUS_CODE, &dwStatus, &dwStatusSize, NULL); dwErrorCode = hResourceHandle ? ERROR_SUCCESS : GetLastError(); dwError = InternetErrorDlg(this->GetSafeHwnd(), hResourceHandle, dwErrorCode, FLAGS_ERROR_UI_FILTER_FOR_ERRORS | FLAGS_ERROR_UI_FLAGS_CHANGE_OPTIONS | FLAGS_ERROR_UI_FLAGS_GENERATE_DATA, NULL); if (dwError == ERROR_INTERNET_FORCE_RETRY) goto resend; DWORD dwNumberOfBytesRead; char sz[1024]; int result; do { result = InternetReadFile(hResourceHandle, sz, 1023, &dwNumberOfBytesRead); sz[dwNumberOfBytesRead] = '\0'; int x = strlen(sz); strResult += sz; memset(sz, 0, 1024); } while(result && dwNumberOfBytesRead != 0); return strResult; I was trying/searching this for two days and finally this is done. For others who want proxy authentication, can refer this code. But still there has to be a way by using CInternetSession as it is wrapper to WinInet API's used above. I am happy now that code is working fine now. Thanks once again for your help.

Thanx for your reply. This will set the proxy, but my problem may be to set the credentials for the proxy ( username and password ). THe way "ises.SetOption()" fails for INTERNET_OPTION_PROXY_USERNAME and INTERNET_OPTION_PROXY_PASSWORD. Is there any other way to set user name and pasword. Thanx once again for ur reply.

The above code works fine if no proxy authentication at server side. It fails as soon as proxy authentication is applied. Please help me to sort out whre i am wrong. Any kind of help appreciated. CInternetSession ises(NULL,1,INTERNET_OPEN_TYPE_PROXY, _T("192.168.9.10:8080"),NULL); CFile* file=new CFile();//There might occur a connection error try { CString url = _T("http://someurl.com/somepath";) DWORD dwFlags = INTERNET_FLAG_TRANSFER_ASCII | INTERNET_FLAG_EXISTING_CONNECT; file = ises.OpenURL(url);//CInternetSession::OpenURL(url) returns a source code in CHttpFile; } catch(CInternetException* e) { //If an error occured, show messagebox with errorcode } //catch(CInternetException *ex) catch(CException *ex) { WCHAR str[500]; DWORD errorCode = GetLastError(); ex->GetErrorMessage(str, GetLastError()); AfxMessageBox(str); } CString result; UINT len=1024; char buf[1024]; source=L""; while(len > 0) { len=file->Read(buf,1024); if(len>0) result.Append(CString(buf),len); } file->Close(); ises.Close(); Thanks and Regards, Amar Mhetre
