"The last installment of JSP best practices was a crash-course
introduction to the JSTL. I showed you how to load JSTL on your Web
container and convert a JSP file to use JSTL tags. While we were at
it, I briefly introduced the c:import tag. Like jsp:include,
c:import uses parameters to intelligently move content around on
your Web site. But unlike the include directive, c:import doesn't
limit its reach to local files.
"This time I'll show you how to convert jsp:params to c:params,
so that you can use the import tag to pass parameters and
manipulate local content just like you did with the include tag. On
top of this basic functionality, you'll also learn how to use
c:import to pull in content from other Web sites. After you've got
a file on your site, it's easy enough to wrap it in your site's
look and feel, which makes importing an easy way to build up your
site in a hurry..."
