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();
}
