-<h3>
-1. INTRODUCTION</h3>
-The REQUEST custom tag library contains tags which can be used to access
-all the information about the HTTP request for a JSP page.
-<h3>
-2. PREREQUISITE SOFTWARE</h3>
-This custom tag library requires no software other than a servlet container
-that supports the JavaServer Pages Specification, version 1.1.
-<h3>
-3. CONFIGURATION INFORMATION</h3>
-Follow these steps to configure your web application with this tag library:
-<p> Copy the tag library descriptor file
-(request/request.tld) to the /WEB-INF subdirectory of your web application.
-<br> Copy the tag library JAR file (request/request.jar)
-to the /WEB-INF/lib subdirectory of your web application.
-<br> Add a <taglib> element to your web
-application deployment descriptor in /WEB-INF/web.xml like this:
-<p> <taglib>
-<br>
-<taglib-uri>http://jakarta.apache.org/taglibs/request-1.0</taglib-uri>
-<br>
-<taglib-location>/WEB-INF/request.tld</taglib-location>
-<br> </taglib>
-<p>To use the tags from this library in your JSP pages, add the following
-directive at the top of each page:
-<p> <%@ taglib uri="http://jakarta.apache.org/taglibs/request-1.0"
-prefix="req" %>
-<p>where "req" is the tag name prefix you wish to use for tags from this
-library. You can change this value to any prefix you like.
-<h3>
-4. TAG DOCUMENTATION</h3>
-This custom tag library includes a number of tags which are documented
-using <a href="javadoc/index.html">javadocs</a>.
-<h3>
-5. USAGE EXAMPLES</h3>
-See the example application (request/request-examples.war) for examples
-of the usage of the tags from this custom tag library.
