If it is not possible or desirable to put the notice in a particular
  file, then You may include the notice in a location (such as a LICENSE
  file in a relevant directory) where a recipient would be likely to
  look for such a notice.

The idea is to automate the acquisition and renewal of these certificates so that you can have **secure HTTPS, for free, forever**.

## HTTPS for Developers { #https-for-developers }

Here's an example of how an HTTPS API could look like, step by step, paying attention mainly to the ideas important for developers.

### Domain Name { #domain-name }

// is encrypted, compressed or uploaded using
// the S3 multipart API then its ETag is not
// necessarily the MD5 of the object content.
//
// For a more detailed description of S3 ETags
// take a look at the package documentation.
type ETag []byte

// String returns the string representation of the ETag.
//
// The returned string is a hex representation of the

        cliRequest.topDirectory = topDirectory;
        // We're very early in the process, and we don't have the container set up yet,
        // so we rely on the JDK services to eventually look up a custom RootLocator.
        // This is used to compute {@code session.rootDirectory} but all {@code project.rootDirectory}
        // properties will be computed through the RootLocator found in the container.

# First Steps { #first-steps }

The simplest FastAPI file could look like this:

{* ../../docs_src/first_steps/tutorial001_py39.py *}

Copy that to a file `main.py`.

Run the live server:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:solid">main.py</u>

  <span style="background-color:#009485"><font color="#D3D7CF"> FastAPI </font></span>  Starting development server 🚀

This could be especially useful during testing, as it's very easy to override a dependency with your own custom settings.

### The config file { #the-config-file }

Coming from the previous example, your `config.py` file could look like:

{* ../../docs_src/settings/app02_an_py39/config.py hl[10] *}

Notice that now we don't create a default instance `settings = Settings()`.

### The main app file { #the-main-app-file }

            // TODO: This breaks the provider
            attributes.put("stylesdir", stylesDir.get().getAsFile().getAbsolutePath());
            attributes.put("stylesheet", "manual.css");
            attributes.put("doctype", "book");
            attributes.put("imagesdir", "img");
            attributes.put("nofooter", true);
            attributes.put("javadocPath", "../javadoc");
            attributes.put("sectanchors", true);

		log.Panicf("no source in tree for import %q (from import %s in %s): %v", name, fromPath, fromDir, err)
	}

	context := w.context
	if context == nil {
		context = &build.Default
	}

	// Look in cache.
	// If we've already done an import with the same set
	// of relevant tags, reuse the result.
	var key string
	if usePkgCache {
		if tags, ok := pkgTags[dir]; ok {
			key = tagKey(dir, context, tags)

	// already have the sizes from the central directory so we can
	// just ignore these.

	return nil
}

func readDirectoryEnd(r io.ReaderAt, size int64) (dir *directoryEnd, baseOffset int64, err error) {
	// look for directoryEndSignature in the last 1k, then in the last 65k
	var buf []byte
	var directoryEndOffset int64
	for i, bLen := range []int64{1024, 65 * 1024} {
		if bLen > size {
			bLen = size
		}

The same example from above, returning an `HTMLResponse`, could look like:

{* ../../docs_src/custom_response/tutorial003_py39.py hl[2,7,19] *}
