Had a smiliar problem here. When using mod_jk, apache does not touch the headers created by Tomcat.
Solution: I wrote a filter that changed the headers after returning from Tomcat and installed this filter into Tomcat. Servlets and filtering (Servlet-Spec 2.3): http://java.sun.com/products/servlet/Filters.html My sample-code (setting an Expires-Header): =============[snip]======================= package com.cr.manuals.filter; import java.text.SimpleDateFormat; import java.util.Calendar; import java.util.Date; import java.util.Locale; import javax.servlet.FilterChain; import javax.servlet.FilterConfig; import javax.servlet.ServletException; import javax.servlet.ServletRequest; import javax.servlet.ServletResponse; import javax.servlet.http.Cookie; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; /** * Servlet implementation class for Servlet: HeaderFilter * */ public class HeaderFilter implements javax.servlet.Filter { private static String PARAM_ADD_TO_CURRENT_MONTH = "ADD_TO_CURRENT_MONTH"; private FilterConfig filterConfig = null; private int months2Add = 0; /* (non-Java-doc) * @see javax.servlet.http.HttpServlet#HttpServlet() */ public HeaderFilter() { super(); } /** * init() : init() method called when the filter is instantiated. * This filter is instantiated the first time j_security_check is * invoked for the application (When a protected servlet in the * application is accessed). */ public void init(FilterConfig aFilterConfig) throws ServletException { filterConfig = aFilterConfig; months2Add = Integer.parseInt(filterConfig.getInitParameter(PARAM_ADD_TO_CURRENT_MONTH)); } /** * destroy() : destroy() method called when the filter is taken * out of service. */ public void destroy() { filterConfig = null; } /** * doFilter() : doFilter() method called before the servlet to * which this filteris mapped is invoked. Since this filter is * mapped to j_security_check,this method is called before * j_security_check action is posted. */ public void doFilter(ServletRequest aRequest, ServletResponse aResponse, FilterChain chain) throws java.io.IOException, ServletException { //System.out.println ("******** filter *******"); HttpServletRequest request = (HttpServletRequest)aRequest; HttpServletResponse response = (HttpServletResponse)aResponse; // call next filter in the chain : let j_security_check authenticate // user response.setHeader("Expires", createExpiresHeader(months2Add)); chain.doFilter(request, response); } /** * Create a String in the format EEE, d MMM yyyy HH:mm:ss z" * Example: Fri, 4 Aug 2006 09:07:44 CEST * The value of the init-parama ADD_TO_CURRENT_MONTH is added to the * month-field of the current date * @return */ private String createExpiresHeader(int someMonths2Add) { SimpleDateFormat sdf = new SimpleDateFormat("EEE, d MMM yyyy HH:mm:ss z", Locale.US); Calendar cal = Calendar.getInstance(); cal.add(Calendar.MONTH, someMonths2Add); long millis = cal.getTimeInMillis(); Date d = new Date(millis); return sdf.format(d); } } =============[snap]======================= HTH Gregor -- what's puzzlin' you, is the nature of my game gpgp-fp: 79A84FA526807026795E4209D3B3FE028B3170B2 gpgp-key available @ http://pgpkeys.pca.dfn.de:11371 --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
