网站header信息 X-Powered-B 如何屏蔽

网站header信息 X-Powered-B 如何屏蔽

Answer 1

对于JSF的应用，你可能会在HTTP的头信息中看到这样的字样：

Server : Apache/2.0.61 (Unix)
X-Powered-By : JSF/1.2

让用户知道这些消息没有太大意义，而且可能造成安全漏洞。需要屏蔽的话可以参考以下步骤：

隐藏Server信息：在apache里控制的,在httpd.conf里加入一行

ServerTokens Prod

隐藏X-Powered-By：在web.xml中加入：

view plaincopy to clipboardprint?
01.<context-param>
02. <param-name>com.sun.faces.sendPoweredByHeader</param-name>
03. <param-value>false</param-value>
04.</context-param>
view plaincopy to clipboardprint?
01.<context-param>
02. <param-name>com.sun.faces.sendPoweredByHeader</param-name>
03. <param-value>false</param-value>
04.</context-param>
<context-param>
<param-name>com.sun.faces.sendPoweredByHeader</param-name>
<param-value>false</param-value>
</context-param>
对于JBoss，需要找到这个文件：<JBOSS_HOME>\server\default\deploy\jboss-web.deployer\conf\web.xml，然后加入以下代码：

view plaincopy to clipboardprint?
01.<filter>
02. <filter-name>CommonHeadersFilter</filter-name>
03. <filter-class>org.jboss.web.tomcat.filters.ReplyHeaderFilter</filter-class>
04. <init-param>
05. <param-name>X-Powered-By</param-name>
06. <param-value>Servlet 2.4; JBoss-4.2.0.GA (build:
07.SVNTag=JBPAPP_4_2_0_GA date=200706281411)/Tomcat-5.5</param-value>
08. </init-param>
09. </filter>
10.↓
11. <filter>
12. <filter-name>CommonHeadersFilter</filter-name>
13. <filter-class>org.jboss.web.tomcat.filters.ReplyHeaderFilter</filter-class>
14. </filter>
