How to let the dispatcher not cache certain component?

[#1]

Hi

  I have a componenet that has some dynamic content. And I don't want to dispatcher to cache this part.  So inspired by http://www.slideshare.net/netceteragroup/dynamic-components-using-singlepageapplication-concepts-in-... (Page 4), This is what I did, under apps/myapp/dynamicComponent, I have a two files, one is dynamicComponent.jsp and the other is dynamicComponent.dynamic.jsp, So in dynamicComponent.dynamic.jsp page, I have some JSP code to render the dynamic content. and in dynamicComponenet.jsp, I am using SSI to include this like this

<div color="red">render this</div> <!--# include virtual="<%=currentNode.getPath().replace("jcr:content","_jcr_content")%>.dynamic.html" />

So I decide to directly hit the page component link like this http://localhost:4505/content/myapp/mypage/_jcr_content/rightPar/dynamicComponent.dynamic.html page, and it didn't show me this red "render this" text, so apparently, it didn't render me anything.

Can someone tell me what is wrong?

SSI includes are a feature of the web server, so you will need a dispatcher in front of your instance in order to use them (see answer at [0]). 

[0] also contains a suggestion to query WCMMode from within your JSP and use a <cq:include to make your content available in author mode, with no dispatcher present.
