FIX: The cache is not updated when you use the SiteCacheRefresh method in the Commerce Server Starter Site if the Starter Site is running in IIS 7.0 integrated pipeline mode

When you try to refresh the site cache for the Starter Site or any customized site that is based on the Starter Site in Microsoft Commerce Server 2007, the site cache is not updated successfully. This problem occurs if the following conditions are true:

• The site is running in Internet Information Services (IIS) 7.0 integrated pipeline mode.
• You try to refresh the site either by using business management applications or directly by using a URL such as the following:
  http://Web_Server_Computer_Name/Site_Name/SiteCacheRefresh.axd?CacheToRefresh=CatalogCache

In the IIS log files, a "http status 302" message is associated with the SiteCacheRefresh.axd entry. Additionally, the redirect for the SiteCacheRefresh.axd file is set to the Login.aspx file.

Note By default, the IIS 7.0 log files are located in the following folder:

The issue occurs because of a problem in the CommerceComponent.dll file that the Starter Site package contains. The Starter Site is using mixed authentication modes. Specifically, the Starter Site is using Forms authentication for protected site pages such as checkout pages and Integrated Windows authentication for the SiteCacheRefresh method. However, IIS 7.0 integrated pipeline mode does not support mixed authentication modes.

To resolve this issue, install this hotfix, and then rebuild the site.

Note For any Commerce Server 2007 site that is using the CommerceComponent.dll file, you can change the code in the MixedAuthenticationModule.cs file in this fix and rebuild the site. The CommerceComponent.dll source code is included in the Starter Site download.
