What is directive?

A directive is way to give some instruction to the container during page translation time.
Three directives:
<%@ directive attribute=”value” %>
However, you can also combine multiple attribute settings for a single directive, as follows:
<%@ directive attribute1=”value1”
attribute 2=”value2”
...
attributeN =”valueN” %>
There are three directives,
1)Page
2)Taglib
3)include
