> Key: HTTPCLIENT-962
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-962
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: Cache
> Affects Versions: 4.1 Alpha2
> Reporter: Jonathan Moore
> Attachments: authorized-responses-2.patch, authorized-responses.patch
>
>
> " When a shared cache (see section 13.7) receives a request
> containing an Authorization field, it MUST NOT return the
> corresponding response as a reply to any other request, unless one
> of the following specific exceptions holds:
> 1. If the response includes the "s-maxage" cache-control
> directive, the cache MAY use that response in replying to a
> subsequent request. But (if the specified maximum age has
> passed) a proxy cache MUST first revalidate it with the origin
> server, using the request-headers from the new request to allow
> the origin server to authenticate the new request. (This is the
> defined behavior for s-maxage.) If the response includes "s-
> maxage=0", the proxy MUST always revalidate it before re-using
> it.
> 2. If the response includes the "must-revalidate" cache-control
> directive, the cache MAY use that response in replying to a
> subsequent request. But if the response is stale, all caches
> MUST first revalidate it with the origin server, using the
> request-headers from the new request to allow the origin server
> to authenticate the new request.
> 3. If the response includes the "public" cache-control directive,
> it MAY be returned in reply to any subsequent request."
> http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.8
> It isn't clear whether the CachingHttpClient is a shared cache or not (it
> depends on where it gets used), so the conservative compliant behavior is to
> assume we are a shared cache. The current implementation is caching responses
> regardless of whether the original requests had Authorization headers or not.
> Patch and discussion forthcoming.
