<p>Still not the movie. Still a nerd.</p>
<hr />
<p>So let's figure out how to add the <code>Link</code> header
for 300 Multiple Choices. As a reminder, <a
href="https://httpwg.org/specs/rfc9110.html#status.300">here's
the spec</a>:</p>
<blockquote>
<p>It is possible to communicate the list using a set of Link
header fields <em><a
href="https://httpwg.org/specs/rfc9110.html#RFC8288">RFC5988</a></em>,
each with a relationship of "alternate", though deployment is a
chicken-and-egg problem.</p>
</blockquote>
<p>So based off some examples for the <code>Link</code> header
in general on <a
href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Link">Mozilla's
docs</a>, and for 300 <code>Link</code> headers specifically <a
href="https://http.dev/300">on http.dev</a>, this is how you
make the <code>Link</code> headers for a 300:</p>
<div class="sourceCode" id="cb1"><pre
class="language-txt"><code class="language-default"><span id="cb1-1"><a href="#cb1-1" aria-hidden="true" tabindex="-1"></a>Link: &lt;/relative/link/like/this&gt;; rel=&quot;alternate&quot;</span>
<span id="cb1-2"><a href="#cb1-2" aria-hidden="true" tabindex="-1"></a>Link: &lt;https://site-one.net/blah/blah/blah&gt;; rel=&quot;alternate&quot;</span></code></pre></div>
<p>Unfortunately, there doesn't seem to be an option for
specifying a preferred choice in the <code>Link</code> header.
So I'll just set mine to these:</p>
<div class="sourceCode" id="cb2"><pre
class="language-txt"><code class="language-default"><span id="cb2-1"><a href="#cb2-1" aria-hidden="true" tabindex="-1"></a>Link: &lt;https://git.askiiart.net/askiiart/askiiart-net&gt;; rel=&quot;alternate&quot;</span>
<span id="cb2-2"><a href="#cb2-2" aria-hidden="true" tabindex="-1"></a>Link: &lt;https://github.com/askiiart/askiiart.github.io&gt;; rel=&quot;alternate&quot;</span></code></pre></div>
<p>And so here's the new nginx config:</p>
<pre class="language-nginx"><code> location /.git {
add_header Location &quot;https://git.askiiart.net/askiiart/askiiart-net&quot;;
add_header Link &#39;&lt;https://git.askiiart.net/askiiart/askiiart-net&gt;; rel=&quot;alternate&quot;; &quot;&#39;;
add_header Link &#39;&lt;https://github.com/askiiart/askiiart.github.io&gt;; rel=&quot;alternate&quot;; &quot;&#39;;
return 300 &#39;&lt;!DOCTYPE html&gt;&lt;html lang=&quot;en&quot;&gt;&lt;head&gt;&lt;meta charset=&quot;utf-8&quot;&gt;&lt;/head&gt;&lt;body&gt;&lt;a href=&quot;https://git.askiiart.net/askiiart/askiiart-net&quot;&gt;Self-hosted&lt;/a&gt;&lt;br&gt;&lt;a href=&quot;https://github.com/askiiart/askiiart-net&quot;&gt;GitHub&lt;/a&gt;&lt;/body&gt;&lt;/html&gt;&#39;;

# 300 Addendum
Still not the movie. Still a nerd.
---
So let's figure out how to add the `Link` header for 300 Multiple Choices. As a reminder, [here's the spec](https://httpwg.org/specs/rfc9110.html#status.300):
> It is possible to communicate the list using a set of Link header fields *[RFC5988](https://httpwg.org/specs/rfc9110.html#RFC8288)*, each with a relationship of "alternate", though deployment is a chicken-and-egg problem.
So based off some examples for the `Link` header in general on [Mozilla's docs](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Link), and for 300 `Link` headers specifically [on http.dev](https://http.dev/300), this is how you make the `Link` headers for a 300:
```txt
Link: </relative/link/like/this>; rel="alternate"
Link: <https://site-one.net/blah/blah/blah>; rel="alternate"
```
Unfortunately, there doesn't seem to be an option for specifying a preferred choice in the `Link` header. So I'll just set mine to these:
```txt
Link: <https://git.askiiart.net/askiiart/askiiart-net>; rel="alternate"
Link: <https://github.com/askiiart/askiiart.github.io>; rel="alternate"
```
And so here's the new nginx config:
```language-nginx
location /.git {
add_header Location "https://git.askiiart.net/askiiart/askiiart-net";
add_header Link '<https://git.askiiart.net/askiiart/askiiart-net>; rel="alternate"; "';
add_header Link '<https://github.com/askiiart/askiiart.github.io>; rel="alternate"; "';
return 300 '<!DOCTYPE html><html lang="en"><head><meta charset="utf-8"></head><body><a href="https://git.askiiart.net/askiiart/askiiart-net">Self-hosted</a><br><a href="https://github.com/askiiart/askiiart-net">GitHub</a></body></html>';
}
```
