+<h1> tipidee: the future </h1>
+
+<p>
+ tipidee is fully functional, and you are encouraged to use it; however, it
+is not yet considered <em>complete</em>. There are some optional features
+of HTTP that would be nice to have, and that may be implemented at some point
+down the line.
+</p>
+
+<h2> Ranges </h2>
+
+<p>
+ <a href="https://datatracker.ietf.org/doc/html/rfc9110#section-14">Ranges</a>
+are a useful part of HTTP when you are serving big files and connections may
+be interrupted and restarted: supporting the <tt>Range:</tt> header can save
+bandwidth, if the client only asks for the parts of the files that it's still
+missing.
+</p>
+
+<p>
+ It hasn't been implemented in tipidee yet because parsing the <tt>Range:</tt>
+header is rather complex, and serving parts of files (as opposed to full files
+sequentially) also requires some extra coding that wasn't deemed worth it for
+an initial release.
+</p>
+
+<h2> HTTP Basic Authentication </h2>
+
+<p>
+ HTTP Basic Auth is ubiquitous; and even
+<a href="https://git.busybox.net/busybox/tree/networking/httpd.c#n120">busybox httpd</a>
+implements it. It sounds silly not to have it; it would be good to add to tipidee.
+</p>
+
+<p>
+ However, how to implement HTTP basic auth in a secure way is not entirely obvious.
+Credentials should not be stored under the document root; passwords should not
+be stored in plain text; the credentials database should have more restrictive
+permissions than the configuration database; and the credentials database
+should be easily regenerated.
+</p>
+
+<p>
+ I'm leaning towards a cdb credentials database, distinct from the configuration
+file; but this requires a <em>second</em> offline text file processor, for the
+credentials file, and adding support for a <em>second</em> cdb mapping in various
+places in <a href="tipideed.html">tipideed</a>. That was more complexity than I
+wanted for an initial release; it's not urgent, it can wait.
+</p>
+
+<h2> ETags </h2>
+
+<p>
+<a href="https://datatracker.ietf.org/doc/html/rfc9110#field.etag">ETags</a> are
+unique identifiers for resources that clients can use to cache data, and only
+download resources they do not have. Like ranges, ETags support can save bandwidth.
+</p>
+
+<p>
+ The problem is that creating ETags is pretty resource-intensive on the server
+side. You have to maintain an ETag database, and update it any time a document
+changes; alternatively, you have to dynamically hash a whole resource before
+deciding if you're serving it or not. Both paths are riddled with traps and
+design challenges, and neither is appealing to a server like tipidee aiming at
+simplicity and efficiency. ETag support may come one day, but it won't be soon.
+</p>
+
+<h2> FastCGI </h2>
+
+<p>
+ If tipidee compares to big Web servers performance-wise, which is the expectation,
+it is quite possible that the performance bottleneck becomes the CGI protocol
+itself, i.e. the need to spawn an additional process for a dynamic request.
+In this case, it would be useful to support other methods of communicating with
+dynamic backends.
+</p>
+
+<p>
+ A module system, or embedding language-specific support into
+<a href="tipideed.html">tipideed</a>, is out of the question, because it goes against
+the design principles of tipidee; however, FastCGI support sounds like a possible
+path to more performance.

+ The way to organize your documents so they can be served by tipideed
+may look a little weird, but there's a logic to it.
+</p>
+
+<p>
+ tipideed serves documents from subdirectories of its working directory,
+and these subdirectories are named according to the host <em>and</em>
+the port of the request.
+</p>
+
+<ul>
+ <li> A request for <tt>https://example.com:1234/doc/u/ment</tt>
+will result in a lookup in the filesystem for
+<tt>./example.com:1234/doc/u/ment</tt>. </li>
+ <li> A request for <tt>https://example.com/doc/u/ment</tt>
+will result in a lookup in the filesystem for
+<tt>./example.com:443/doc/u/ment</tt>. </li>
+</ul>
+
+<p>
+The fact that the port is always specified allows you to have
+different document sets for the same host on different ports:
+more flexibility.
+</p>
+
+<p>
+ However, most of the time, you <em>don't</em> want different
+document sets for different ports. You want the same document
+sets for ports 80 and 443, and that's it. And you don't want
+to have both a <tt>domain example.com:80</tt> section and a
+<tt>domain example.com: 443</tt> section in your
+<a href="tipidee.conf.html">/etc/tipidee.conf</a>, with
+duplicate information.
+</p>
+
+<p>
+ That is why you are allowed to make your document roots
+<em>symbolic links</em>, and resource attributes declared in
+the configuration file are always looked up with the
+<em>canonical path</em>. In other words, the common case
+would be:
+</p>
+
+<ul>
+ <li> Have your document root in <tt>./example.com</tt>, a
+real directory. </li>
+ <li> Declare your resource attributes under a
+<tt>domain example.com</tt> section in your configuration file. </li>
+ <li> Have a <tt>./example.com:80</tt> symlink pointing to
+<tt>example.com</tt>, if you want to serve <tt>example.com</tt>
+under plaintext HTTP. </li>
+ <li> Have a <tt>./example.com:80</tt> symlink pointing to
+<tt>example.com</tt>, if you want to serve <tt>example.com</tt>
+under HTTPS. </li>
+</ul>
+
+<p>
+ This system allows you to share documents across virtual hosts
+without fear of misconfiguration. You can symlink any document
+under <tt>example.com</tt> to any name under <tt>example.org</tt>;
+if the path via <tt>example.com</tt> is the canonical path, then
+your resource will still get the correct attributes, defined in a
+<tt>domain example.com</tt> section, even if it is accessed via an
+<tt>example.org</tt> URL. You will not inadvertently expose source
+code for CGI scripts, for instance.
+</p>
+
+<p>
+ You can do wild things with symbolic links. However, anything
+that does not resolve to a file in a document root under tipideed's
+current working directory will be rejected. If an attacker symlinks
+your <tt>/etc/passwd</tt> file, tipideed will keep it safe.
