# Rewrite

Rewrite middleware rewrites the URL path based on provided rules. It can be helpful for backward compatibility or just creating cleaner and more descriptive links.

## Signatures

```go
func New(config ...Config) fiber.Handler
```

    Rules: map[string]string{
      "/old":   "/new",
      "/old/*": "/new/$1",
    },
  }))
  
  app.Get("/new", func(c *fiber.Ctx) error {
    return c.SendString("Hello, World!")
  })
  app.Get("/new/*", func(c *fiber.Ctx) error {
