Bug 143014 – [WK2] Responses with 404 HTTP Status Code should be cacheable by default

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKit2

[Chris Dumez]

Responses with 404 HTTP Status Code should be cacheable by default according to RFC 7231:
"""
   A 404 response is cacheable by default; i.e., unless otherwise
   indicated by the method definition or explicit cache controls (see
   Section 4.2.2 of [RFC7234]).
""" [1]

[1] http://tools.ietf.org/html/rfc7231#section-6.5.4

The new WebKit Network cache does not currently cache these, even if Cache-Control headers allow us to do so.

If you don't need permutations you can just define the tests as simple array and call runTests directly.
