Debian系统下JSP的缓存策略如何设置

在Debian系统下，JSP（Java Server Pages）的缓存策略可以通过修改Tomcat服务器的配置来实现。以下是一些常见的缓存策略设置方法：

1. 修改web.xml文件

你可以在你的Web应用程序的web.xml文件中设置缓存相关的参数。例如：

<web-app>
    <!-- 设置JSP文件的缓存时间 -->
    <jsp-config>
        <jsp-property-group>
            <url-pattern>*.jsp</url-pattern>
            <el-ignored>true</el-ignored>
            <page-encoding>UTF-8</page-encoding>
            <scripting-invalid>false</scripting-invalid>
            <include-prelude>/WEB-INF/jsp/common/header.jspf</include-prelude>
            <include-coda>/WEB-INF/jsp/common/footer.jspf</include-coda>
            <trim-directive-whitespaces>true</trim-directive-whitespaces>
            <default-content-type>text/html</default-content-type>
            <buffer>8kb</buffer>
