What is the difference between include directive and include action?
| Include directive | Include action |
|---|---|
| The include directive, includes the content of the specified file during the translation phase–when the page is converted to a servlet. | The include action, includes the response generated by executing the specified page (a JSP page or a servlet) during the request processing phase–when the page is requested by a user. |
| The include directive is used to statically insert the contents of a resource into the current JSP. | The include standard action enables the current JSP page to include a static or a dynamic resource at runtime. |
| Use the include directive if the file changes rarely. It’s the fastest mechanism. | Use the include action only for content that changes often, and if which page to include cannot be decided until the main page is requested. |
