In Windows SharePoint Services 3.0 and Microsoft Office SharePoint Server 2007 environments, the Web Parts containing search results display invalid URLs for each item. This problem occurs when the SharePoint farm is configured to use reverse proxy publishing (off-box SSL termination). The URLs show HTTPS as the protocol. However, the URLs incorrectly include ":80" as the port address.
To resolve this issue, apply the following updates:
