<span id="variant.Normal" class="variant small-section-header"><a href="#variant.Normal" class="anchor field"></a><span id='Normal.v' class='invisible'><code>Normal</code></span></span><div class='docblock'><p>Indicates a normal closure, meaning that the purpose for
which the connection was established has been fulfilled.</p>
</div><span id="variant.Away" class="variant small-section-header"><a href="#variant.Away" class="anchor field"></a><span id='Away.v' class='invisible'><code>Away</code></span></span><div class='docblock'><p>Indicates that an endpoint is &quot;going away&quot;, such as a server
going down or a browser having navigated away from a page.</p>
</div><span id="variant.Protocol" class="variant small-section-header"><a href="#variant.Protocol" class="anchor field"></a><span id='Protocol.v' class='invisible'><code>Protocol</code></span></span><div class='docblock'><p>Indicates that an endpoint is terminating the connection due
to a protocol error.</p>
</div><span id="variant.Unsupported" class="variant small-section-header"><a href="#variant.Unsupported" class="anchor field"></a><span id='Unsupported.v' class='invisible'><code>Unsupported</code></span></span><div class='docblock'><p>Indicates that an endpoint is terminating the connection
because it has received a type of data it cannot accept (e.g., an
endpoint that understands only text data MAY send this if it
receives a binary message).</p>
</div><span id="variant.Abnormal" class="variant small-section-header"><a href="#variant.Abnormal" class="anchor field"></a><span id='Abnormal.v' class='invisible'><code>Abnormal</code></span></span><div class='docblock'><p>Indicates an abnormal closure. If the abnormal closure was due to an
error, this close code will not be used. Instead, the <code>on_error</code> method
of the handler will be called with the error. However, if the connection
is simply dropped, without an error, this close code will be sent to the
handler.</p>
</div><span id="variant.Invalid" class="variant small-section-header"><a href="#variant.Invalid" class="anchor field"></a><span id='Invalid.v' class='invisible'><code>Invalid</code></span></span><div class='docblock'><p>Indicates that an endpoint is terminating the connection
because it has received data within a message that was not
consistent with the type of the message (e.g., non-UTF-8 [RFC3629]
data within a text message).</p>
</div><span id="variant.Policy" class="variant small-section-header"><a href="#variant.Policy" class="anchor field"></a><span id='Policy.v' class='invisible'><code>Policy</code></span></span><div class='docblock'><p>Indicates that an endpoint is terminating the connection
because it has received a message that violates its policy. This
is a generic status code that can be returned when there is no
other more suitable status code (e.g., Unsupported or Size) or if there
is a need to hide specific details about the policy.</p>
</div><span id="variant.Size" class="variant small-section-header"><a href="#variant.Size" class="anchor field"></a><span id='Size.v' class='invisible'><code>Size</code></span></span><div class='docblock'><p>Indicates that an endpoint is terminating the connection
because it has received a message that is too big for it to
process.</p>
</div><span id="variant.Extension" class="variant small-section-header"><a href="#variant.Extension" class="anchor field"></a><span id='Extension.v' class='invisible'><code>Extension</code></span></span><div class='docblock'><p>Indicates that an endpoint (client) is terminating the
connection because it has expected the server to negotiate one or
more extension, but the server didn't return them in the response
message of the WebSocket handshake. The list of extensions that
are needed should be given as the reason for closing.
Note that this status code is not used by the server, because it
can fail the WebSocket handshake instead.</p>
</div><span id="variant.Error" class="variant small-section-header"><a href="#variant.Error" class="anchor field"></a><span id='Error.v' class='invisible'><code>Error</code></span></span><div class='docblock'><p>Indicates that a server is terminating the connection because
it encountered an unexpected condition that prevented it from
fulfilling the request.</p>

reconnect, and if it does, it should use a randomized delay of 5-30
seconds between attempts.</p>
</div><span id="variant.Again" class="variant small-section-header"><a href="#variant.Again" class="anchor field"></a><span id='Again.v' class='invisible'><code>Again</code></span></span><div class='docblock'><p>Indicates that the server is overloaded and the client should either
