Dynacache Tip: Exclude JSP fragment from cache

Scenario:

1. You are caching a JSP in cachespec.xml, lets call it "parent.jsp".

2. You have configured "parent.jsp" to consume sub-fragments.

3. There is a JSP being included by parent.jsp, lets call it "child.jsp"

4. The file is being included using the <c:import> tag

5. You don't want to cache child.jsp at all
6. You don't want parent.jsp to consume child.jsp into its cache

Solution:

Add the following line in child.jsp:

<% ((com.ibm.websphere.servlet.cache.ServletCacheResponse)response).setDoNotConsume(true); %>

This way gets around having to add child.jsp to cachespec.xml and setting do-not-consume=true.
