SUMMARY
=======
Microsoft Posting Acceptor is a server add-on component in the Windows NT Option Pack (NTOP) that enables the use of HTTP Post (RFC 1867) to publish content to your Web site.
MORE INFORMATION
================
To get Posting Acceptor to work with as few steps as possible, perform the following steps:
1. Install Posting Acceptor using one of the following methods:
- Install Posting Acceptor during the NTOP installation.
-OR-
- Run the NTOP setup and specify Add/Remove.
2. In either of the above methods, specify the installation of Posting Acceptor, by doing the following:
a. Select Microsoft Site Server Express 2.0.
b. Click Show Subcomponents.
c. Select Publishing - Posting Acceptor.
d. Click OK and complete the wizard.
3. Verify that the Cpshost.dll file is in your Scripts folder.
4. Create a new directory named Uploads and give it at least NTFS Add permissions to valid users, but ensure that the "Everyone" and IUSR_COMPUTERNAME accounts do not have rights to the folder.
5. Create a new virtual directory that points to the new Uploads directory with write access.
6. Create a new text file named Postacpt.asp in your Scripts folder and paste the following HTML code into it:
<SCRIPT RUNAT=SERVER LANGUAGE="JavaScript">
if (Request.ServerVariables("LOGON_USER") == '')
Response.Status('401 Access Denied');
</SCRIPT>
<html>
<body>
<form enctype="multipart/form-data"
action="/scripts/cpshost.dll?PUBLISH" method="POST">
<center><table>
<tr>
<td align="left">File to upload</td>
<td align="left"><input name="file" type="file" size="20"></td>
</tr>
<tr>
<td align="left">Destination URL</td>
<td align="left">
<input name="TargetURL" value="/uploads/" size="20">
<input type="Submit" value="Upload..."></td>
</tr>
<table></center>
</form>
</body>
</html>
Notes on the above code sample:
- The JavaScript code forces a browser to authenticate. You can remove this code to allow anonymous posting, otherwise you will need to add users/groups as specified in the step above.
- The form uses a new input of type "file" that should display a Browse button on the Web page.
7. Browse the page at "http://localhost/scripts/postacpt.asp" and upload a file to verify the correct functionality.
