Welcome

This document describes the Microsoft Posting Acceptor server add-on and provides important information about the product.

Users of this tool should be familiar with the Microsoft Windows NT operating system.

What Does the Posting Acceptor Server Add-on Do?

Microsoft Posting Acceptor is a server add-on tool that enables Web content providers using HTTP Post (RFC 1867) to publish content to your hosting service.

Hardware and Software Requirements

'Hardware'

Windows NT Server 4.0:

486/33 or higher Intel processor or Alpha RISC processor compatible with Windows NT

16 MB of memory (64 MB recommended)

10 MB of hard drive space plus space for users' uploaded files

Windows NT Workstation 4.0:

486/33 or higher Intel processor or Alpha RISC processor compatible with Windows NT

16 MB of memory (64 MB recommended)

10 MB of hard drive space plus space for users' uploaded files

'Software'

Windows NT Server 4.0 (with or without Content Replication System):

Microsoft Internet Information Server (IIS) 3.0, or later.

Active Server Pages

Windows NT Workstation 4.0 (no Content Replication System support):

Windows NT Workstation with Peer Web Services 3.0, or later.

Active Server Pages*

Active Server Pages (ASP) is not required, but will allow for automatic-routing of the posting client to the proper page for a particular client tool. Microsoft IIS and Personal Web Server (versions 1.0a or later) provide ASP in their respective installations.

Known Issues

If you try to use Internet Explorer on the machine to which you installed the Posting Acceptor, you may receive the following error:

Error initializing the cache. Shutdown all programs and run ScanDisk or ChkDsk. Delete the cache, cookies and history directories in your Windows directory and restart Internet Explorer. If the problem persists, reinstall Internet Explorer.

This is a known bug in Microsoft Internet Explorer (IE). For more information, see the Microsoft Knowledge Base article:

106387 HOWTO: Share Kernel Objects Between Processes

Due to a bug in Internet Information Server (IIS) 4.0 beta 1, the Posting Acceptor will not work properly on a system with IIS 4.0 beta 1.
- Readme.htm
- Image.gif
- Default.htm
folder2:
- Readme.htm
- Bar.htm
and your destination URL is http://servername/stuff then committing http://servername/stuff/readme.htm twice will fail, because the local directory has not been set. To set the local directory, right click the ActiveX Upload Control, select Upload Settings, and type in the path name of the appropriate local directory.

Enabling or Disabling Mapping Modules

To enable or disable a mapping module, you must set the value of the HKLM/Software/Microsoft/WebPostAcceptors/CPSHost/Mappers registry key. To enable a mapping module, set the value to 1. To disable it, set the value to 0.

New Features

Posting Acceptor now includes repost.asp, a sample post-processing page. This sample shows a simple application of the Posting Acceptor post-processing feature. When it is called from uploadn.asp (the form-based RFC1867 page for Netscape clients), it shows the posting status of an upload. After Posting Acceptor is installed, the sample page can be found in the scripts directory. NOTE: IE clients should use the sample page uploadx.asp.

Using the Microsoft ActiveX Upload Control

The Microsoft ActiveX Upload Control can be used in a variety of ways to allow for the simple drag and drop publishing of Web content. The control allows for publishing over a variety of protocols. It enters the various pieces of information usually needed to publish content by means of FTP or even through the Web Publishing Wizard. Instead, the server administrator sets this information in the Web page that calls the Microsoft ActiveX Upload Control.

This document explains the various ways to tie the control into products such as Microsoft Posting Acceptor and the Microsoft Site Server Content Replication System.

When authoring a page to use the Upload Control, the Web Publishing Provider can be defined in several different ways. The standard method is to create a PostInfo file on the server that hosts the content and have it define the provider to use (by CLSID) and the relevant parameters. Details of all Microsoft Service Provider parameters are found in the PostInfo section at the end of this document.

Sample PostInfo File

The following sample uses the HTTP Post Provider and Microsoft Posting Acceptor:

<% Response.Buffer = TRUE %>
<% if (Len(Request.ServerVariables("LOGON_USER")) = 0 )
then %>
<% Response.Status = "401 Unauthorized" %>
<B> Error: Access is denied. </B> <P>
<% else%> 
Version=1.5 
[{8B14B770-748C-11D0-A309-00C04FD7CFC5}]
PostingURL="http://<%= 
Request.ServerVariables("SERVER_NAME") 
%>/scripts/cpshost.dll?PUBLISH" 
TargetURL="http://<%= 
Request.ServerVariables("SERVER_NAME") %>/users/<%= Request.ServerVariables("LOGON_USER") %>" 
<% end if %>

The PostInfo file is retrieved by the Web Publishing API by querying the default document of the server hosting the Web page using the Upload Control Web server and parsing for the PostInfo meta tag. This tag needs to be added to that document in the following format:

<META name="postinfo" content="/scripts/postinfo.asp">

The PostInfo file can have any extension and live anywhere on any Web server. The content value can be a relative path or any fully qualified URL. It can be dynamically generated based on the retrieving user's data or anything else you wish to use.

Another option is to define this information in the Web page hosting the control. This is done by using the SetBindingParam call within the page. See below for a definition and an example of the SetBindingParam call.

The Upload Control allows you to define the site information as temporary or permanent. A temporary site would be used when much of the underlying site information might change from user post to post. A permanent site would be used when the target URL, posting URL, and so on are to remain constant from user post to post, such as in a setup for a user's personal Web page. The following is a list of all the properties and methods exposed by the ActiveX Upload Control.

AboutBox

HRESULT AboutBox();

Displays the Upload Control About Box.

FoundPostInfo

int FoundPostInfo();

Property is set to true if, during a CreateTempBinding or CreatePermBinding call, WebPost found a PostInfo file on the server.

SetBindingParam

void SetBindingParam( 
IN BSTR bstrParamName, 
IN BSTR bstrParamValue);

This method allows the content author to set the Provider-specific WebPost server variables that would normally be in a PostInfo file. These variables are described for each provider in the section on POSTINFO files found below.

bstrParamName
This is the parameter to be set for this provider binding.

bstrParamValue
This is the value for the above parameter.

CreateTempBinding

HRESULT CreateTempBinding(
   IN BSTR bsDestUrl,

   IN BSTR bsProvCLSID
);

Creates a temporary site and binds to it. This site will be deleted when the user shuts down the browser.

bsDestUrl
Address of a null-terminated string that contains the destination URL for the site. This is where the files dropped on the Upload Control will be posted. This may not be NULL or empty.

bsProvCLSID
Address of a null-terminated string that contains the CLSID of the provider that will handle this site. This may be NULL or empty, in which case the Upload Control will attempt to find a PostInfo file or auto-bind to an appropriate provider.

CreatePermBinding

CreatePermBinding( 
IN BSTR bsBindingName, 
IN BSTR bsDestUrl,  
IN BSTR bsProvCLSID 
);

Creates a permanent site and binds to it. The site information is persistent--it will remain on the user's machine even after the browser is shut down.

bstrBindingName
Address of a null-terminated string that contains the site name. This may not be NULL or empty.

bstrDestUrl
Address of a null-terminated string that contains the destination URL for the site. This is where the files dropped on the Upload Control will be posted. This may not be NULL or empty.

bstrProvCLSID
Address of a null-terminated string that contains the CLSID of the provider that will handle this site. This may be NULL or empty, in which case the Upload Control will attempt to find a PostInfo file or auto-bind to an appropriate provider.

UploadedFile

void UploadedFile(

    BSTR bstrFileName,

    long lErrorCode,

    BSTR bstrErrMsg
);

This event is raised after the object dropped on the Upload Control has either been successfully uploaded or the transmission has failed.

bstrFileName
This is the name of the file that was uploaded or failed to upload.

lErrorCode
This is the status code associated with the file upload. The value is S_OK if the upload was successful, or contains the HRESULT errorcode if the upload failed.

bstrErrMsg
This returns the error message related to the error.

Sample Web Page #1

The following sample page uses the CRS Provider, creates a permanent site definition on the user's machine, does not need a PostInfo file, and will return an error dialog box to the user should a problem occur when posting the content.

PostInfo Parameters

The following tables list the parameters supported by each Microsoft Service Provider. When writing a PostInfo file for a server, as many parameters as possible should be specified for each Service Provider the server will support, in order to minimize the amount of information that must be entered by a user.

The DefaultPage parameter is handled by the Web Publishing API and is not listed under the individual Service Providers below.

The CLSID's for the Microsoft Service Providers

Service Provider	CLSID
FTP Provider	{02B5E1D1-8B7C-11D0-AD45-00AA00A219AA}
CRS Provider	{FFCF1E40-7978-11D0-B1C9-00AA006DCDF4}
HTTP Post Provider	{8B14B770-748C-11D0-A309-00C04FD7CFC5}
Front Page Provider	{2C93FE81-E03A-11cf-832F-00A0C90A43A8}

Parameter	Example Value	Meaning
Authentication	NTLM	The name of the security package to use when authenticating against the server.
ServerName	Myserver	The name of the CRS server.

FTP Service Provider

Note that if present, the special string "$USERNAME" will be replaced with the name of the account used to log in to the server during publishing. This string can be used in the ServerName and Subfolder values.

The ConnectTimeout, ConnectRetries, SendTimeout, and ReceiveTimeout, were made site parameters to allow dynamic adjustment of the waiting behavior on network calls. However, a typical PostInfo file will probably not need to include these parameters. The values listed under "Example Value" below for these four parameters are the defaults.

Parameter	Example Value	Meaning
Server Name	Myserver	The name of the FTP server.
Subfolder	home/users/$USERNAME	The path on the FTP server where files should be saved. Note that $USERNAME will be replaced with the "UserName" value.
ConnectTimeout	30000 (msec)	The length of the timeout to use when connecting to the server.
ConnectRetries	5	The number of retries to make when connecting to the server.
Authentication	NTLM	The name of the security package to use when authenticating against the server.
SendTimeout	30000 (msec)	The length of the timeout for all network packets sent.
ReceiveTimeout	30000 (msec)	The length of the timeout for all network packets received.
BasePath	-	This value is obsolete. If present on a site key that was used with version 1.1 of the Web Publishing Wizard, it will be upgraded to "Subfolder" the first time the FTP Provider binds to the site.
FtpServerName	-	This value is obsolete. If present on a site key that was used with version 1.1 of the Web Publishing Wizard, it will be upgraded to "ServerName" the first time the FTP Provider binds to the site.

HTTP POST Service Provider

Parameter	Example Value	Meaning
PostingURL	http://myserver/scripts/cpshost.dll?PUBLISH	The URL of the HTTP POST acceptor.
TargetURL	http://myserver/users	The URL where the uploaded files should be placed.
