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

## Завантаження Кількох Файлів

Можна завантажувати кілька файлів одночасно.

Вони будуть пов’язані з одним і тим самим "form field", який передається у вигляді "form data".

Щоб це реалізувати, потрібно оголосити список `bytes` або `UploadFile`:

    } catch (Throwable reflectionFailure) { // sneaky checked exception
      // Some Android 5.0.x Samsung devices have bugs in JDK reflection APIs that cause
      // getDeclaredField to throw a NoSuchFieldException when the field is definitely there.
      // For these users fallback to a suboptimal implementation, based on synchronized. This will
      // be a definite performance hit to those users.

Guava provides two different "flavors": one for use on a (Java 8+) JRE and one
for use on Android or by any library that wants to be compatible with Android.
These flavors are specified in the Maven version field as either `33.5.0-jre` or
`33.5.0-android`. For more about depending on Guava, see
[using Guava in your build].

To add a dependency on Guava using Maven, use the following:

```xml
<dependency>
