### Creating the `Settings` only once with `lru_cache` { #creating-the-settings-only-once-with-lru-cache }

Reading a file from disk is normally a costly (slow) operation, so you probably want to do it only once and then reuse the same settings object, instead of reading it for each request.

But every time we do:

```Python

### Links

Use the following rules for links (apply both to Markdown-style links ([text](url)) and to HTML-style <a href="url">text</a> tags):

- For relative URLs, only translate the link text. Do not translate the URL or its parts.

Example:

Source (English):
