Re: Tuckey Rewrite URL and infinite loop exception trace for Tomcat 7.0.57

[Kiran Badi]

I resolved it.My bad, to and from rule were having same url mapping and I
feel thats the reason it filter was recursively called and finally
resulting into stackoverflow error.

Tuckey Rewrite URL and infinite loop exception trace for Tomcat 7.0.57

[Kiran Badi]

Hi,

I am having some issues with  Tuckey Rewrite URL/Tomcat 7.0.57 and for some
reasons I believe I am not getting it correct. It seems to me that I am
getting into infinite loop somewhere.Not sure why but conditions do match.


 Hello World! This is a link I am trying
to clean it.

Below is test servlet.


 protected void processRequest(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
try (PrintWriter out = response.getWriter()) {
String[] params = request.getPathInfo().substring(1).split("/");
System.out.println(params[0]);
String testid = request.getParameter("testid");
RequestDispatcher rd =
request.getRequestDispatcher("/WEB-INF/views/Hello.jsp");
rd.include(request, response);
}
}



http://www.tuckey.org/res/dtds/urlrewrite4.0.dtd;>






The rule means that requests to /test/status/ will be
redirected to /rewrite-status
the url will be rewritten.

/test/status/
%{context-path}/rewrite-status


 Sample redirect
[0-9]
^/GetServlet(.*)$
/GetServlet/testid/%{parameter:testid}




The outbound-rule specifies that when response.encodeURL is
called (if you are using JSTL c:url)
the url /rewrite-status will be rewritten to /test/status/.

The above rule and this outbound-rule means that end users
should never see the
url /rewrite-status only /test/status/ both in thier location
bar and in hyperlinks
in your pages.

/rewrite-status
/test/status/
