i have read about .tag files in head first servlet/jsp.
they mentioned that .tag files are just glorified includes.
is it same like <jsp:include> and <c:import>?
can any one please tell me whats the difference between the two.
and also what is the main purpose of .tag files?

Tag files allow you to create custom actions (tags) using JSP markup rather than writing a tag handler in Java code. They are well-suited to tags that emit lots of template text or that need to perform JSP-like actions.

They are superior to include or imports for creating re-usable components because data can be formally passed to the tags via the attributes. With includes and imports, data passing is informal via scoped variables.
