SUMMARY
=======
This step-by-step guide explains the correct ASP syntax for retrieving user
authentication information from a Web site visitor. This information can only be
captured if the site uses Basic Authentication, Windows NT Challenge Response
(NTLM), or Windows Integrated Authentication.
Requirements
------------
- A Windows-based Web server running IIS 4.0 or IIS 5.0
- A text or ASP editor such as Notepad or Microsoft Visual InterDev.
The Code
--------
To capture the visitor's domain and login, paste the following code into your ASP
page. If the page also contains HTML, paste this code above the HTML tag.
<%
Dim strUser
strUser = Request.ServerVariables("LOGON_USER")
Response.Write strUser
%>
This code will capture the user's domain and login, and then display it in the
browser.
Making the Code More Useful
---------------------------
Now that you have a method for capturing the user's login information, you may
want to store it somewhere. The steps in this section demonstrate how to create
a text file and write the information to it. Note that this method is only one
of many that use Request.ServerVariables.
1. Right-click Start, and then click Explore to open Windows Explorer.
2. In Windows Explorer, click File, point to New, and then click Folder.
3. This will create a new folder with the name area highlighted. Type "ASP"
(without the quotation marks), and then press ENTER to name the new folder
"ASP."
4. Paste the following code into your ASP page. If the page also contains HTML,
paste this code above the HTML tag.
<%
Dim objFSO, strUser, objFile
strUser = Request.ServerVariables("LOGON_USER")
set objFSO = Server.CreateObject("scripting.FileSystemObject")
set objFile = objFSO.CreateTextFile("C:\asp\test.txt", true)
objFile.WriteLine strUser
objFile.Close
Response.Write strUser
%>
5. This code will write the user's login information to a text file that is
automatically created in the ASP folder (the folder you created in step 3).
