Kim Shepherd commented on DS-768:
---------------------------------
More progress.. I'm now displaying 404s using the exception2html.xslt page, not
a generic Tomcat 404. Screenshot attached.
So hopefully the only thing left to do is discuss the merits of throwing
ResourceNotFound vs. manually setting http status in transformers, and how to
theme our exceptions a bit better.
(though personally, I'd rather have an ugly error page throwing a true 404
status code than a nice-looking "Page not found" page with a 200 OK or 304 NOT
MODIFIED in its headers)

> Key: DS-768
> URL: https://jira.duraspace.org/browse/DS-768
> Project: DSpace
> Issue Type: Bug
> Components: XMLUI
> Affects Versions: 1.6.0, 1.6.1, 1.6.2, 1.7.0
> Reporter: Tim Donohue
> Assignee: Kim Shepherd
> Priority: Major
> Fix For: 1.8.0

> In DSpace 1.7.0 RC1, the XMLUI "Page Not Found" page responds with a 200 OK,
> rather than the necessary 404 Not Found error.
> For example:
> http://demo.dspace.org/xmlui/NOTAVALIDPATH
> I believe this used to function properly in 1.6.x, but it seems to be broken
> now.
> Obviously, we want this to return a 404 Not Found, in order to ensure that
> search engines do not index "Page Not Found" responses.
> Furthermore, it has been discovered that all other XMLUI Error pages (Cocoon
> Errors or Invalid Continuation errors) also respond with 200 OK. In
> addition, it seems this affects all 1.6.x versions of DSpace, as the same
> responses can be found on http://dspace.mit.edu (currently running 1.6.0 with
> patches), and http://researchspace.auckland.ac.nz (currently running 1.6.2
> with patches).
