Content that doesn't change or that doesn't change often should be included using a mechanism which won't try to interpret it. Specifically, <%@ include file="..." %>, which includes the file in the JSP servlet translation phase (i.e. it happens once), should be used instead of <jsp:include page="..." />, which includes the page on the file, when the content is being served to the user.

Noncompliant Code Example

<jsp:include page="header.jsp">  <!-- Noncompliant -->

Compliant Solution

<%@ include file="header.jsp" %>
