Creating a redirect page for users without SPNEGO support
Create an HTML page to redirect users whose web browsers do not support SPNEGO.
About this task
To create an HTML page to redirect users to, complete the following steps:
Procedure
- Create an HTML page with HTML such as that shown in the
following example:
<!DOCTYPE HTML PUBLIC "-//W3C/DTD HTML 4.0 Transitional//EN"> <META HTTP-EQUIV="Content-Type" CONTENT="text/html"> <!-- Notes: - This file should be served from an unprotected website. Alternatively, it can be loaded from the WebSphere Application Server file system. - Any imbedded graphics/javascript/css must be loaded from an unprotected website. - This file is loaded after WebSphere Application Server is initialized. If changes to this file are necessary, restart WebSphere Application Server. - This file is returned whenever the SPNEGO TAI receives an NTLM token for any application in the cell. In other words, this file is generic for all applications. However, by using the document.location Javascipt , we can get the original URL, and redirect to that original URL with the "?noSPNEGO" text added - thus forcing the standard application userid/password challenge. --> <html> <head> <script language="javascript"> var origUrl=""+document.location; if (origUrl.indexOf("noSPNEGO")<0) { if (origUrl.indexOf('?')>=0) origUrl+="&noSPNEGO"; else origUrl+="?noSPNEGO"; } function redirTimer() { self.setTimeout("self.location.href=origUrl;",0); } </script> <script language="javascript"> var titleNode = document.createElement('title'); titleNode.innerHTML = 'Redirect to'; var origUrlText = document.createTextNode(origUrl); titleNode.appendChild(origUrlText); document.getElementsByTagName('head')[0].appendChild(titleNode); </script> </head> <body onLoad="redirTimer()"/> </html>
- Save the file as, for example, NoSpnegoRedirect.html on a publicly-accessible directory on your web server. For example, IHS_server/htdocs/NoSpnegoRedirect.html.
