is invoked which is mapped with userservlet.
i counld not found use case where ContentServlet is invoked.When the ContentServlet is invoked and what is it's utility ?

The ContentServlet is in the process of being deprecated. The only piece of functionality in ContentServlet but not UserServlet that I can think of is the ability to fetch a remote FileUpload.

Unless you're doing this, please use UserServlet instead.
