THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!

This example just rewrites all incoming requests to /struts to /tapestry. In your AppModule or any other Tapestry-IoC module class:
| Code Block | ||||
|---|---|---|---|---|
| ||||
public static void contributeURLRewriter(OrderedConfiguration<URLRewriterRule> configuration)
{
URLRewriterRule rule = new URLRewriterRule()
{
public Request process(Request request, URLRewriteContext context)
{
final String path = request.getPath();
if (path.equals("/struts"))
{
request = new SimpleRequestWrapper(request, "/tapestry");
}
return request;
}
public RewriteRuleApplicability applicability()
{
return RewriteRuleApplicability.INBOUND;
}
};
configuration.add("myrule", rule);
}

The URLRewriteContext (added in 5.1.0.4) provides additional information for rewriting, particularly in the context of rewriting generated link urls. In the following example, we'll reconfigure the url used to render pages. Whereas the previous examples used separate rules for handling inbound and outbound rewriting, this demonstration will utilize a single rule for both scenarios. To simplify the example, we will assume that every page is named "XXXPage" (UserPage, TransactionPage, IndexPage, etc.). This naming convention also means that we don't have to worry about tapestry's auto-stripping of "index" from URLs, because our page would be IndexPage, rather than Index.
