A path component may resemble or map exactly to a <a href="/wiki/Path_(computing)" title="Path (computing)">file system path</a> but does not always imply a relation to one. If an authority component is defined, then the path component must either be empty or begin with a slash (<code>/</code>). If an authority component is undefined, then the path cannot begin with an empty segment—that is, with two slashes (<code>//</code>)—since the following characters would be interpreted as an authority component.<sup id="cite_ref-rfc2396_19-0" class="reference"><a href="#cite_note-rfc2396-19"><span class="cite-bracket">[</span>16<span class="cite-bracket">]</span></a></sup><sup class="reference nowrap"><span title="Location: §3.3">: §3.3 </span></sup></li></ul> <dl><dd>By convention, in <b>http</b> and <b>https</b> URIs, the last part of a <i>path</i> is named <b><link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1238216509"><span class="vanchor"><span id="pathinfo"></span><span class="vanchor-text">pathinfo</span></span></b> and it is optional.
