<p>Create or replace a resource.</p>
<p>The behavior of this function varies depending on whether a body is provided.</p>
<p>The function <code>put/3</code> expects either a content-length or content-type header to indicate that a body will be sent afterwards. The body can then be sent using <a href="../gun.data">gun:data(3)</a>.</p>
<p>The function <code>put/4,5</code> sends the entire request, including the request body, immediately. It is therefore not possible to use <a href="../gun.data">gun:data(3)</a> after that. You should provide a content-type header. Gun will set the content-length header automatically.</p>
<h2 id="_arguments">Arguments</h2>
<dl><dt>ConnPid</dt>
<dd><p>The pid of the Gun connection process.</p>
</dd>
<dt>Path</dt>
<dd><p>Path to the resource.</p>

<h2 id="_return_value">Return value</h2>
<p>A reference that identifies the newly created stream is returned. It is this reference that must be passed in subsequent calls and will be received in messages related to this new stream.</p>
