Wt

In case of dynamic resources being present on the page, this is requested from the application using the application's entrypoint, with request=resource&resource={id}.
Of course, by that point the application has already been shut down for bots. This will cause a new WApplication being spun up, to serve the non-existing resource.
In some cases, this will result in a 404, but if the entrypoint would match an WApplication path, that can cause a whole page being served.

Many bots will then iteratively go over the response again, and again find those resources, leading to them spamming a server with requests.
It has been decided that bots will get 404 responses in case of dynamic resources. They are still able to request static resources.
