Thread:Project:Support desk/Is http://de.wikipedia.org/?curid=2809853 an expoloit or can this be considered as a legitimate stable redirect ?/reply (6)

a) Are there special keywords at http://www.mediawiki.org/wiki/Bugzilla for topics related to the stability of the setup of WikiMedia Foundation servers? Any bug about Wikimedia server set up would be in the Wikimedia product of bugzilla. (vs normal bugs in MediaWiki product). Some Wikimedia server config related bugs end up in RT, which is secret (Don't ask me why its secret, I've never really understood. Something about billing info goes in there too)

b) Could all relevant parts of the apache configuration required to achieve similar results at other MediaWiki installation be documented? The actual config files are at http://noc.wikimedia.org . Any set up where url parameters on the root url gets forwarded to index.php should work in the fashion you are looking for.

Could all required testcases be added to MediaWiki in order to assure that such urls would not be broken / invalid in the future? No, you cannot add test cases to MediaWiki for testing software that is not MediaWiki. One could add a test case to verify that urls of the form http://en.wikipedia.org/w/index.php?curid=1234 don't break, but that's as close as you can get.

It was mentioned only because "oldid" adds some "headers" also curid will add noindex tags that stop google from indexing non-canonical versions of the url. (Not quite a header, but probably what you're thinking of).
