POST Request Resolving

Hi Everyone,

now i am learning CQ5 with a training material. I did the exercise with the Flexigrid, which fetches the user information via a POST request.

The request looks like this "http://localhost:4502/content/training_site/en/company/jcr:content/par /usergrid.json", aber the component

provides the script "usergrid.json.POST.jsp" and "usergrid.jsp".

I can't understand why the script "usergrid.json.POST.jsp" will be chosen for this POST request. Due to Cheat Sheet of CQ "usergrid.jsp" should be chosen.

Who can help me to explain this, how does it work in this case ? Does the POST work in an another way ?

Thanks a lot.

Edwin.
