Using the Code
What we can do with the
OnSendResponse routine is to modify the realm.
Keep it simple. There are two GUI front-ends to configure this filter. The first is called regedit.exe and the second is called regedt32.exe, you will find it on your server ;o). Create two subkeys under HKEY_LOCAL_MACHINE\SOFTWARE\ called "LEAN Software Production\IISModifyRealm", and under this, a
String value Realm; the Value data will be the realm.
- Copy the IISModifyRealm.dll file to the %WINDIR%\System32\inetsrv directory.
- Make sure the System account has execute rights on the filter DLL file.
- Start "Internet Information Services" from the Control Panel\Administrative Tools, and open the Properties of your Default Web Site.
- Click the ISAPI Filter Tab and Add the Filter by typing a name and the full path to the Filter DLL (%WINDIR%\System32\inetsrv\IISModifyRealm.dll).
- Restart the WWW service.
