Hide page version query parameters
Is there a built-in way to hide page version parameters (e.g. ?12) in
Wicket 1.5? If not, is it possible to write a custom IRequestMapper that
does so without screwing up proper request handling?

You can also add a <link rel="canonical"
href="http://example.com/your-canonical-url"/> to the head to instruct the
search engines to find the proper page.

All the links had it from the start. The crawlers from the big
companies (Google, Bing etc) obey it, but some smaller ones do not.
Anyways, I fixed the problem by filtering the bad parameters with
urlrewritefilter. So no more internal server errors.

I should have been more clear, this case wasn't directly related to
the page version parameter, but to clean urls.
The thing is that I had a few stateful links in the frontpage which
changed the page stylesheet. Now when I have removed the links, I'm
seeing some crawlers still trying to request them.
For example, a get request to
/?0-1.ILinkListener-stylechooser-style1&wicket:interface=:1:stylechooser:style2::ILinkListener::
throws this with Wicket 1.5.3:

The urls with the page id can be bookmarked. If the requested version
of the page is not available then a new version is created and
delivered.

Plain and simple, I like clean urls that can be bookmarked.
Also some of the search engine bots save the crawled urls (with
parameters) and try to access them at a later time. I found this out
when I updated one of my sites and now I'm seeing a lot of 500
Internal error responses in my web server logs.

Re: Hide page version query parameters

Yes, thats right, stateless pages do not have version number,
but normally it is not so easy to make pages stateless, we always had
problems with that.
But if you change your render strategy to redirect to render, the uri in the
browser does not change and you always have clean uris. Thats how we solved
the problem.
Just try this in your Applications init Method:
getRequestCycleSettings().setRenderStrategy(RenderStrategy.REDIRECT_TO_RENDER);
You should be aware of the side effects of different render strategies, just
look in Javadoc of RenderStrategy.

Everything is possible.
The new IRequestMapper are easily extensible and you can even use your own one.
By default this special parameter is set so when the user presses F5
(Refresh) the page Wicket will deliver the same version of the page.
Otherwise a new instance will be created without the knowledge of the
exact version.
Why do you want to hide this parameter ?

OK, thanks for the info.
If I remember correctly, in Wicket 1.4 stateful pages had also clean
urls if the page was mounted to a certain path, i.e. the page version
number was stored somewhere behind the scenes. I'm guessing this isn't
possible anymore in Wicket 1.5?

This is not correct.
The page id is encoded in the url only for stateful pages. Make your
page stateless and it wont be there.

Hi,
Did you find a way to remove the page version parameter?
I'm also trying to figure out how to achieve that in Wicket 1.5. In 1.4 it
was easy since, mounting the page with mountBookmarkablePage was enough.
