tomcat 配置问题，自定义 Response Headers

[clark_kidd]

我想用 tomcat 做为一个静态页的 web 服务器，所以在 webApp 中放了一些静态页和文件。
问题来了，我可以对 tomcat 进行配置，使浏览器在对静态资源请求时，加入固定的 Response Headers 吗？
还是说，我一定要弄个自定义 filter 才行？

据我所知，IIS 可以

tomcat好像没有这个功能

纯粹做静态服务器,nginx和apache岂不是更简单,你说的这些功能静态服务器都是支持的

写了个Filter，导出成 jar 后，放到 tomcat\lib 目录下，然后修改了 tomcat\conf\web.xml，重启tomcat解决了

package cn.common.java.utility;

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class StaticCacheControl implements Filter {

	public void destroy() {}

	public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain chain) throws IOException, ServletException {

		HttpServletRequest request      = (HttpServletRequest)servletRequest;
		HttpServletResponse response    = (HttpServletResponse)servletResponse;   
        
		response.setHeader("cache-control", "no-cache");

		chain.doFilter(request, response);
	}

	public void init(FilterConfig filterConfig) throws ServletException {}
}

	<filter>
		<filter-name>staticFilter</filter-name>
		<filter-class>cn.common.java.utility.StaticCacheControl</filter-class>
	</filter>

	<filter-mapping>
		<filter-name>staticFilter</filter-name>
		<url-pattern>*.js</url-pattern>
	</filter-mapping>

完美解决，撒分
