<p>There are two ways to select the HTTP version of an incoming connection:</p>
<ul>
<li>One is to rely on the ALPN information that is provided when using a TLS (HTTPS); both
versions are supported automatically when using either of the <code>.bind_rustls()</code> or
<code>.bind_openssl()</code> methods.</li>
<li>The other is to read the first few bytes of the TCP stream. This is the only viable approach
for supporting H2C, which allows the HTTP/2 protocol to work over plaintext connections. Use
the <code>.bind_auto_h2c()</code> method to enable this behavior.</li>

<h5 id="hostname-resolution"><a class="doc-anchor" href="#hostname-resolution">§</a>Hostname Resolution</h5>
<p>When <code>addrs</code> includes a hostname, it is possible for this method to bind to both the IPv4
and IPv6 addresses that result from a DNS lookup. You can test this by passing
<code>localhost:8080</code> and noting that the server binds to <code>127.0.0.1:8080</code> <em>and</em> <code>[::1]:8080</code>. To
bind additional addresses, call this method multiple times.</p>
<p>Note that, if a DNS lookup is required, resolving hostnames is a blocking operation.</p>
<h5 id="worker-count-1"><a class="doc-anchor" href="#worker-count-1">§</a>Worker Count</h5>
<p>The <code>factory</code> will be instantiated multiple times in most scenarios. The number of
instantiations is number of <a href="struct.HttpServer.html#method.workers" title="method actix_web::HttpServer::workers"><code>workers</code></a> × number of sockets resolved by
<code>addrs</code>.</p>
<p>For example, if you’ve manually set <a href="struct.HttpServer.html#method.workers" title="method actix_web::HttpServer::workers"><code>workers</code></a> to 2, and use <code>127.0.0.1</code>
as the bind <code>addrs</code>, then <code>factory</code> will be instantiated twice. However, using <code>localhost</code>
as the bind <code>addrs</code> can often resolve to both <code>127.0.0.1</code> (IPv4) <em>and</em> <code>::1</code> (IPv6), causing
the <code>factory</code> to be instantiated 4 times (2 workers × 2 bind addresses).</p>
<p>Using a bind address of <code>0.0.0.0</code>, which signals to use all interfaces, may also multiple
the number of instantiations in a similar way.</p>
<h5 id="typical-usage"><a class="doc-anchor" href="#typical-usage">§</a>Typical Usage</h5>
<p>In general, use <code>127.0.0.1:&lt;port&gt;</code> when testing locally and <code>0.0.0.0:&lt;port&gt;</code> when deploying
(with or without a reverse proxy or load balancer) so that the server is accessible.</p>
