public class EqualsParameterTag

extends javax.servlet.jsp.tagext.TagSupport

JSP Tag equalsParameter, used to determine if a Request parameter equals the value of the "match" tag attribute.

Includes the body of the tag if the parameter equals the value of the "match" tag parameter.

You can set the optional tag parameter value to true or false. The body of the tag is included if equalsParameter matches the value.

You can set the optional tag parameter ignoreCase to true or false. If ignoreCase is set to true, then the comparison between the request parameter and the "match" tag attribute will not be case-sensitive.
