to better explain
usually static resources are handled by the application server. the server
knows it is serving a file and thus sets the last modified date of the
resource to the last modified date of a file.
so lets say you have
/myapp/images/foo.gif
and you map your wicket servlet to /*
what happens is that when a request comes in for /myapp/images/foo.gif it
will match the wicket servlet - so now it is wicket servlet's job to serve
this file to the browser. now we are nice enough to provide support for this
- but obviously we cannot do as good a job as the application server which
has a lot more context.
so we recommend mapping the servlet to something like /app/* so that
foo.gifwill be processed by the application server and only
wicket-specific
requests are processed by the servlet.
in 2.0 what we did was instead of using a servlet use a filter
the advantage of a filter is that unlike a servlet it can choose not to
process the request and let whatever is next in chain try. so when using a
wicket filter and a request comes in for foo.gif the filter chooses not to
process it because it knows it is not a wicket-related request. since the
filter didnt process it it falls on to the application server to try, and
then it works.
someone mind putting this on the wiki?

when using wicket 1.x and the WicketServlet (maybe we backport the filter

Don't have an servlet mapping of /*
Because then the wicket servlet must do everything also as you notice the
static resources
Those resources should be handled by the right (default?) servlet of your
app server.
But with a servlet it is all or nothing. In 2.0 we fixed this then we also
supply a filter
so that we can pass it through to the next filter/servlet when we (the
filter) doesn't want this request.
so servlet mapping of /* is strongly not recommended!!
