Original request filter ver. 1.1

This is a Java servlet filter (as per Servlet API 2.3). This filter lets you keep in the request scope all the attributes from the original HTTP request: javax.servlet.forward.request_uri, javax.servlet.forward.context_path, javax.servlet.forward.servlet_path javax.servlet.forward.path_info, javax.servlet.forward.query_string. So JSP page will be always aware about the original request regardless of the forwarding chain.

How to use it:

a) download originalrequestflt.jar and save it in WEB-INF/lib

b) describe this filter in web.xml.
 


<filter>
  <filter-name>OriginalRequestFilter</filter-name>
  <filter-class>com.cj.original.OriginalRequestFilter</filter-class>
</filter>

c) describe a mapping for this filter in web.xml. E.g.:
 


<filter-mapping>
  <filter-name>OriginalRequestFilter</filter-name>
  <url-pattern>*</url-pattern>
</filter-mapping>

in this example filter will be on for the each .jsp file. So in your JSP page you can use for example request.getAttribute("javax.servlet.forward.query_string") for getting an original query string.

   For downloading:

    Original request package:  originalrequestflt.jar
