It is impossible to switch off URL caching if https protocol is used -------------------------------------------------------------------- Key: DROOLS-66 URL: https://issues.jboss.org/browse/DROOLS-66 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Environment: BRMS 5.3.1 Reporter: Alessandro Lazarotti Assignee: Mark Proctor Fix For: 6.0.0.Alpha1 It is impossible to switch off URL caching if https protocol is used When used https to load resources from HTTP, a conditional mistake try to cache the content even though CACHE_DIR is null: // class org.drools.io.impl.UrlResource public InputStream getInputStream() throws IOException { (...) if (lastMod > 0 && lastMod > lastRead) { if (CACHE_DIR != null && url.getProtocol().equals("http") || url.getProtocol().equals("https")) { //lets grab a copy and cache it in case we need it in future... cacheStream(); } } (...) } IF only "https" was evaluated as true - ((false && false) || true) - so the exit will be true, which should be not the expected behaviour That code should be: if (CACHE_DIR != null && (url.getProtocol().equals("http") || url.getProtocol().equals("https"))) { //lets grab a copy and cache it in case we need it in future... cacheStream(); }
