网址是否已被重写？ 曲棍球-urlrewrite

Question

I use http://tuckey.org/urlrewrite/ library

I am trying to detect if the URL of the page has been rewritten or not,

I come up with something like this:

if(req.getRequestURL().toString().contains("?")) {
  //do stuff
}

But the url of the page that is rewritten is the same as the normal one:

request.getRequestURL().append("?").append(request.getQueryString()).toString();

So my question is: how to detect if the URL has been rewritten or not?

Answer 1

As far as I know, Tuckey doesn't provide any direct way of testing wheter it actually rewrote a URL or not.

I think your best bet is to add an additional request parameter on the rewrite rule and then test for that parameter.

Something like:

<to type="redirect">/some/url?rewritten</to>

and then something like

boolean rewritten = request.getParameter("rewritten") != null;
