Required. The full url path that the request will be sent to.

This string must begin with either "http://" or "https://". Some examples
are: `http://acme.com` and `https://acme.com/sales:8080`. Cloud Tasks will
encode some characters for safety and compatibility. The maximum allowed
URL length is 2083 characters after encoding.

The `Location` header response from a redirect response [`300` - `399`]
may be followed. The redirect is not counted as a separate attempt.
</pre>

<code>string url = 1 [(.google.api.field_behavior) = REQUIRED];</code>

@return The bytes for url.
