Subject [jira] Created: (HTTPCLIENT-958) client cache currently allows incomplete responses to be passed on to the client
Date Fri, 25 Jun 2010 16:11:53 GMT
client cache currently allows incomplete responses to be passed on to the client
--------------------------------------------------------------------------------

                 Key: HTTPCLIENT-958
                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-958
             Project: HttpComponents HttpClient
          Issue Type: Bug
          Components: Cache
            Reporter: Jonathan Moore
            Priority: Minor


Per the HTTP/1.1 spec:

"A cache that receives an incomplete response (for example, with fewer bytes of data than
specified in a Content-Length header) MAY store the response. However, the cache MUST treat
this as a partial response. Partial responses MAY be combined as described in section 13.5.4;
the result might be a full response or might still be partial. A cache MUST NOT return a partial
response to a client without explicitly marking it as such, using the 206 (Partial Content)
status code. A cache MUST NOT return a partial response using a status code of 200 (OK)."

(http://www.w3.org/Protocols/rfc2616/rfc2616-sec13.html#sec13.8)

For example, if a 200 response shows up with 128 bytes in the body but a Content-Length header
of 256, the cache MUST NOT pass this through unchanged.
