Why is handleSessionRestorationErrorInContext called here?

What I _think_ is happening:


Sounds resonable (as you always do ;-)

Tell that to my wife!  :-P



When writing context.request() to the log in handleSessionRestorationErrorInContext I see that the request is for the following url: "/cgi-bin/WebObjects/nettlogg.woa/wo/myimage.gif"

I'd try to trap things like that before they get to the session handling code. One place is in rewrite rules if using Apache. Another
Application.dispatchRequest before calling super. Just return a 404 response.

Application.dispatchRequest sounds like a good place.

But how should I know when to return a 404 response? I could look for "nettlogg.woa/wo/*.gif" in the request url and then I know I should return status 404. Does that sound like a resonable way of knowing when to return status 404?


That is roughly what I was thinking. You could probably just reject any URL ending in .gif, .jpg, .jpeg etc. etc. Another way to do this is to compare to a correctly formed URL: nettlogg.woa/wo/<context ID>.<element ID>.


Context ID should be one or more digits, element ID is more variable. It should be easy to look for <digits>. after any /wo/ in a URL with regex.
