MCMS 2002 Console Writes Postback From Action Address by Using an Absolute URI (813867)


The information in this article applies to:

  • Microsoft Content Management Server 2002

SYMPTOMS

Microsoft Content Management Server (MCMS) 2002 DefaultConsole writes postback from an action address by using an absolute URI. If you reverse proxy the MCMS 2002 server by using a proxy server that does not forward the original header to the MCMS server, clients cannot use the Web author console. When you view the HTML ouptut of an MCMS page, you see references to the server name that look similar to the following:
<base href="http://servername/WoodgroveNet/Templates/Home.aspx?wbc_purpose=Basic&NRMODE=Unpublished...">
...
var __CMS_CurrentUrl = 'http://servername/WoodgroveNet/Templates/Home.aspx?wbc_purpose=Basic&NRMODE=Unpublished...';
...
__CMS_PostbackForm.action = 'http://servername/CMSNoURI/Templates/CmsTemplate1.aspx?wbc_purpose=Authoring&NRMODE=Update&...';

CAUSE

Because some proxy servers do not forward the original HTTP header to the MCMS server, the reverse proxy server uses the server NetBIOS name to perform the HTTP request to the MCMS 2002 server. When the client switches to Edit mode, the client cannot use the default console because the Console and RobotMetaTag classes use an aboslute URI with the server name instead of an absolute path and query string.

WORKAROUND

Based on the WoodgroveNet sample site, you can make the following changes to the solution to remove the absolute URI in the content that is served:
  1. Change the BASE HREF tag:
    1. Edit the WoodgroveNet\UserControls\HeadTags.ascx.cs code-behind file.
    2. Add the following line of code in the Page_Load function definition:
      RobotMetaTag1.RenderBaseHref = false;
  2. Change the PostBackForm addresses. To do this, in each template of the site, override the RegisterClientScriptBlock function to remove all occurrences of "http://servername" if the script block contains the "__CMS_PostbackForm" string. Insert this new function definition in the Page public class definition. After you make the change, the code looks similar to the following:

    namespace WoodgroveNet.Templates
{
	Public class Home : System.Web.UI.Page
	{
		#region CMS Placeholders
		#region Public Properties
		#region Page Load
		
		#region override RegisterClientScriptBlock added by yanno
		public override void RegisterClientScriptBlock(string blockname, string script)
		{
			Regex cmsregex = new Regex(@"__CMS_PostbackForm");
			Regex httpregex = new Regex(@"(http://[^/]*)");

			if ( cmsregex.IsMatch(script,1) )
				script = httpregex.Replace(script, "");
			
			base.RegisterClientScriptBlock(blockname, script);
		}
		#endregion override RegisterClientScriptBlock

		#region Web Form Designer generated code
	}
}

  3. Change the Login/Logout Header button:
    1. Edit the WoodgroveNet\UserControls\Header.ascx.cs code-behind file.
    2. Change the HeaderLoginLogoff_Click function at line 63 from
      Response.Redirect(Request.Url.AbsoluteURI);
      to: 
      Response.Redirect(Request.Url.PathAndQuery);

STATUS

Microsoft has confirmed that this is a bug in the Microsoft products that are listed in the "Applies to" section. This problem was corrected in Content Management Server 2002 Service Pack 1.

MORE INFORMATION

This fix changes the behavior of the Console class but does not change the way the RobotMetaTag object formats the BASE HREF address. To prevent the BASE HREF address from being rendered, follow the steps in the "Workaround" section.
