Thanks Zoran for sharing your approach, greatly appreciated, I'm
thinking about implementing a similar interceptor, and maybe replace the
i18n one so work is done implicitly with only a change in struts.xml and
the new interceptor.

Hi Guys,
We simplified it for struts to use a simple interceptor. Can’t show the
exact code due to legal crap, but here’s the overview.
In our base action we have a String called requestString, with
appropriate getters and setters. We also have a Map<String, String> of
unsafe URL’s and their safe counterparts. For example if the unsafe url
was deleteObject.action it’s safe option would be listObject.action
The interceptor uses the following code:
if(unsafeUrls.get(request.getRequestURI()) != null)
responseUrl = unsafeUrls.get(request.getRequestURI());
else
responseUrl = request.getRequestURI();
StringBuffer rStr = new StringBuffer(responseUrl);
rStr.append(“?”);
for (Iterator iter = request.getParameterMap().keySet().iterator();
iter.hasNext();) {
String key = (String) iter.next();
if (!"request_locale".equalsIgnoreCase(key)) {
if (request.getParameter(key) != null) { // you can also include
your own parameter specific exceptions. With the tag we used to have
a comma delimited list of excluded parameters.
rStr.append(key);
rStr.append("=");
rStr.append((String) request.getParameter(key));
rStr.append("&");
}
}
}
action.setRequestString(sStr.toString());
And then on the page we have:
<div class=”localeFlag”><a
href="${requestString}&request_locale=${localeOpt.lang}" ><img
src="${pageContext.request.contextPath}/image/icons/${localeOpt.lang}_flag.gif"
alt="<s:text name="%{“select.”+ attr.localeOpt.lang}" />"
title="<s:text name="%{“select.”+ attr.localeOpt.lang}" />" /></a></div>
I had to modify the code to satisfy our people but let me know if you
have any questions. We use a complex parameter filtering process to
unsure that security isn’t compromised.
We’ve had to do quite a bit of i18n which has involved implementing DB
based properties and tighter integration with S2 and spring.

Hi Zoran,
would you mind sharing the code of this tag? It would be helpful to me,
as somehow I've been able to link to the same sction with an empty url
tag but unable to retain params. Thanks!
