That might be so, but practically speaking this doesn't occur. Try this
yourself and you will notice that "path" is always reset to a value of
one on every server restart. For an unknown reason, it is not resumed on
restart. Can someone investigate this?

Server restart should work
All sessions are serialized to disk and read back in.

Even if the images are dynamically generated, couldn't we
serialize the
highest "path" value used on shutdown and reuse it on startup? Consider
the following use-case:
- Images are dynamically generated from a DB
- Expiration headers are set to cache the images for one day on the
client end
- Wicket's resource cache expiration is also set to one day
So ... while the images are dynamic, they are also cached
(for a
limited period of time). This use-case works fine if the server is never
restarted. All we'd need is a simple fix to make it work across
restarts.
