# Utiliser des middlewares avancés { #advanced-middleware }

Dans le tutoriel principal, vous avez vu comment ajouter des [middlewares personnalisés](../tutorial/middleware.md) à votre application.

Vous avez également vu comment gérer [CORS avec le `CORSMiddleware`](../tutorial/cors.md).

Dans cette section, nous allons voir comment utiliser d'autres middlewares.

+ No Markdown
+ The first PR comment (this one) is wrapped at 76 characters, unless it's
  really needed (ASCII art, table, or long link)
+ If there is a corresponding issue, add either `Fixes #1234` or `Updates #1234`
  (the latter if this is not a complete fix) to this comment
+ If referring to a repo other than `golang/go` you can use the

// DefaultValue returns the default value of current column.
