[jira] [Created] (HTTPCLIENT-1290) 304 cached response never reused with If-modified-since conditional requests

Francois-Xavier Bonnet created HTTPCLIENT-1290:
--------------------------------------------------

             Summary: 304 cached response never reused with If-modified-since conditional requests
                 Key: HTTPCLIENT-1290
                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1290
             Project: HttpComponents HttpClient
          Issue Type: Bug
          Components: Cache
    Affects Versions: 4.2.3
            Reporter: Francois-Xavier Bonnet


Steps to reproduce the problem:
- cache is empty
- send a conditional If-modified-since request
- backend server responds with a 304 Not modified (the response does not contain the "Last-modified" header, this conforms to rfc 2616 chapter 10.3.5)
- the response is stored in the cache
- send another conditional If-modified-since request
- as the cache entry does not contain a Last-modified header to match with the If-modified-since request header, the cache considers the entry cannot be used and sends a request again to the backend server
