How to work around servers returning wrong HTTP codes #17
Description
https://polarion.oslc.itm.kth.se/polarion/oslc/services/catalog returns 200, for example and gives you a login page.
One approach is to request https://polarion.oslc.itm.kth.se/.well-known/resource-that-should-not-exist-whose-status-code-should-not-be-200 beforehand (see protocol-registries/well-known-uris#13 and oslc-op/oslc-specs#460) but it only shows if the server is completely off its meds.
Should we go radical and consider any non-RDF response to be an error?
