> Key: HTTPCLIENT-1147
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1147
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: Cache
> Affects Versions: 4.2 Alpha1
> Reporter: Craig
> Fix For: 4.2 Alpha2
>
>
> Set up HttpClient-Cache like this:
> final String cacheDir = "cachedir";
> HttpClient cachingHttpClient;
> final CacheConfig cacheConfig = new CacheConfig();
> cacheConfig.setSharedCache(false);
> cacheConfig.setMaxObjectSizeBytes(262144); //256kb
> if(! new File(cacheDir, "httpclient-cache").exists()){
> if(!new File(cacheDir, "httpclient-cache").mkdir()){
> throw new RuntimeException("failed to create httpclient cache directory: " + new File(cacheDir, "httpclient-cache").getAbsolutePath());
> }
> }
> final ResourceFactory resourceFactory = new FileResourceFactory(new File(cacheDir, "httpclient-cache"));
> final HttpCacheStorage httpCacheStorage = new ManagedHttpCacheStorage(cacheConfig);
> cachingHttpClient = new CachingHttpClient(client, resourceFactory, httpCacheStorage, cacheConfig);
> Then make a request:
> final HttpGet get = new HttpGet(url);
> final HttpResponse response = cachingHttpClient.execute(get);
> final StatusLine statusLine = response.getStatusLine();
> if (statusLine.getStatusCode() >= 300) {
> if(statusLine.getStatusCode() == 404)
> throw new NoResultException();
> throw new HttpResponseException(statusLine.getStatusCode(),
> statusLine.getReasonPhrase());
> }
> response.getEntity().getContent();
> Everything worked as expected.
> Now delete the cache directory ("cachedir/httpclient-cache" in this example).
> And make the same request again.
> Actual:
> Caused by: java.lang.IllegalStateException: Content has been consumed
> at org.apache.http.entity.BasicHttpEntity.getContent(BasicHttpEntity.java:84)
> at org.apache.http.conn.BasicManagedEntity.getContent(BasicManagedEntity.java:100)
> Expected:
> HttpClient shouldn't throw an exception - it should just perform the request again acting like a cache miss.
