It's bookmarked pages that avoid new page creation isn't it?

no just the opposite
bookmarkable url will create a new page (which can be state full or
stateless)

Hi,
- the scenario is this:
jmeter stress-testing (10 simultaneous users with no ramp-up and an
infinite-loop cycle) a wicket application (extends SpringWebApplication) by
only refreshing the HomePage.
- the result is:
observing the disk, the pagemap file for each session (10 items), there is
Just because it's the same page class it doesn't mean it's the same
page instance. How does the URL that you invoke look like?

the url is this: http://localhost:9090/test/
if you constantly target exactly that url
then that will be a new page everytime because thats just a bookmarkable
url.
not an instance url.

if this is the behaviour by default, then, how do you avoid a DoS attack? i
mean, to put an example, if a simple app like this receives thousand of
users just refreshing the home page, then the pagestore will be
overloaded... may this become a disk I/O overhead and its other possible
consequences.
You have the exact same problem with every stateful application. If
you want to avoid a DoS attack (which isn't really always possible)
you need a good firewall.

there's no way to avoid repetition of this page in pagestore? i guess

Have you set it unversioned? How about trying to make it stateless?

You can make your home page stateless. Of course that limits what
components you can put on it.

Would it be a good idea to be able to specify the pagestore limits on a
per-wicket-session base?
So you could for example increase the page store limits once a user has
successfully authenticated.
DoS web clients usually don't go through the mess to authenticate first. Also

dos attack is very rude scenario? ok, a more realistic scenario would be -
as happens here - an app that has a very huge amount of users during only
one week per year (about 40k users connecting to this app for subscriptions
and checking some personal information). let's say

SetVersioned(false) does not help with new page instances being created.
