FIX: The cache is not updated when you use the SiteCacheRefresh method if you specify host headers for a Commerce Server 2007 application that is hosted by a Web farm
Article ID: 958771 - View products that this article applies to.
Consider the following scenario:
This issue occurs because of an issue in Microsoft.commerceserver.shared.dll. When you use the SiteCacheRefresh method, Commerce Server 2007 builds a URL. This URL is based on a value in the MSCS_Admin database. If the host header is configured for multiple servers as it is in the Web farm scenario, the URL is inaccurate. Therefore, the Commerce Server cache may not be updated successfully.

AlwaysRefreshURLWithHTTPregistry entry, the
BuildCacheRefreshURLWithHostNameregistry entry, and the Enable HTTPS check box in Commerce Server manager to control which mode to refresh the cache and which method is used to build the correct cache refresh URL.
If AlwaysRefreshURLWithHTTP=0 and the Enable HTTPS check box is clear or if AlwaysRefreshURLWithHTTP=1, sitecacherefresh uses HTTP mode.
In HTTP mode, with BuildCacheRefreshURLWithHostName set to different value, the URL is built in varying ways as follows:
