Add hostname as a cache-id in Dynacache

Sample below shows how to do it. It can be useful if the same store is accessed using different domain names, one for external customers and another for internal support when they place orders on behalf of a customer. In such case, you might need to create separate cache entries to avoid problems that might raise up because of hard coded links in any of the JSPs or any other logic that might break if you store one cache entry for both.

<component id="host" type ="header">
     <required>false</required>
</component>
