will fail early. The default value is `httpcookiemaxnum=3000`. Setting
`httpcookiemaxnum=0` will allow the cookie parsing to accept an indefinite
number of cookies. To avoid denial of service attacks, this setting and default
was backported to Go 1.25.2 and Go 1.24.8.

Go 1.26 added a new `urlstrictcolons` setting that controls whether `net/url.Parse`
allows malformed hostnames containing colons outside of a bracketed IPv6 address.

# Query Parameters and String Validations { #query-parameters-and-string-validations }

**FastAPI** allows you to declare additional information and validation for your parameters.

Let's take this application as example:

{* ../../docs_src/query_params_str_validations/tutorial001_py310.py hl[7] *}

### Proxy-Forwarded-Header aktivieren { #enable-proxy-forwarded-headers }

Sie können FastAPI CLI mit der *CLI-Option* `--forwarded-allow-ips` starten und die IP-Adressen übergeben, denen vertraut werden soll, um diese Forwarded-Header zu lesen.

Wenn Sie es auf `--forwarded-allow-ips="*"` setzen, würde es allen eingehenden IPs vertrauen.

# Full Stack FastAPI Template { #full-stack-fastapi-template }

Templates, while typically come with a specific setup, are designed to be flexible and customizable. This allows you to modify and adapt them to your project's requirements, making them an excellent starting point. 🏁

You can use this template to get started, as it includes a lot of the initial set up, security, database and some API endpoints already done for you.

Swagger UI also allows other configurations to be **JavaScript-only** objects (for example, JavaScript functions).

FastAPI also includes these JavaScript-only `presets` settings:
