+/**
+ * HTTP client that does queries in the background
+ *
+ * The handler method takes the following arguments: an arbitrary pointer, an
+ * HTTP response code, the URL queried, whether or not the message body was
+ * stored on disk, and the message body.
+ *
+ * If stored on disk, the body string contains the path and the file must be
+ * moved or deleted by the receiver when it's done. If an error occurs, the
+ * response code will be negative and the body will be the error message.
+ *
+ * All headers in the returned headers map will have their header names
+ * converted to lower case, e.g. "content-type".
+ *
+ * Currently only the "http" transport is guaranteed to be supported on all
+ * platforms.
