Notice how no connect events are fired for the second call. It reused the connection from the first request for dramatically better performance.

## Multiple File Uploads { #multiple-file-uploads }

It's possible to upload several files at the same time.

They would be associated to the same "form field" sent using "form data".

To use that, declare a list of `bytes` or `UploadFile`:

		sort 演算子の利用方法は sort:&lt;field&gt;.&lt;order&gt; になります。
		&lt;order&gt; は asc または desc で昇順・降順を指定できます。
		たとえば、Fess を含むドキュメントでサイズの降順にソートしたい場合、次のように入力します。
		<pre>Fess sort:content_length.desc</pre>
		標準で利用可能なフィールドは created, content_length および last_modified になります。
