ch.uzh.ifi.attempto.echocomp
Class HeaderControlFilter

java.lang.Object
  extended by ch.uzh.ifi.attempto.echocomp.HeaderControlFilter
All Implemented Interfaces:
javax.servlet.Filter

public class HeaderControlFilter
extends java.lang.Object
implements javax.servlet.Filter

This filter is a workaround for the problem that Firefox 3.0.0 to 3.0.4 somehow sends wrong XML headers to the server. See the discussion in this thread of the Echo forum. This code is inspired by the workaround proposed by the user "Nadir".

In order to apply this filter, the following lines have to be added to web.xml:

 <filter>
   <filter-name>headercontrol</filter-name>
   <filter-class>ch.uzh.ifi.attempto.echocomp.HeaderControlFilter</filter-class>
   <init-param>
     <param-name>request.reencoding</param-name>
     <param-value>UTF-8</param-value>
   </init-param>
 </filter>
 
 <filter-mapping>
   <filter-name>headercontrol</filter-name>
   <url-pattern>*</url-pattern>
 </filter-mapping>
