## Details

The first `"/static"` refers to the sub-path this "sub-application" will be "mounted" on. So, any path that starts with `"/static"` will be handled by it.

  # the same changes in start up args in istio-ingress pods.
  #
  # TCP connection timeout between Envoy & the application, and between Envoys.
  connectTimeout: 1s
  #
  ### ADVANCED SETTINGS #############
  # Where should envoy's configuration be stored in the istio-proxy container
  configPath: "/etc/istio/proxy"
  binaryPath: "/usr/local/bin/envoy"
  # The pseudo service name used for Envoy.

# Middleware

There are several middlewares available provided by Starlette directly.

Read more about them in the [FastAPI docs for Middleware](https://fastapi.tiangolo.com/advanced/middleware/).

::: fastapi.middleware.cors.CORSMiddleware

It can be imported from `fastapi`:

```python
from fastapi.middleware.cors import CORSMiddleware
```

::: fastapi.middleware.gzip.GZipMiddleware

It can be imported from `fastapi`:

//	db.Where(User{Name: "jinzhu"}).Attrs(User{Email: "******@****.***"}).FirstOrInit(&user)
//	// user -> User{Name: "jinzhu", Age: 20}
//
// [FirstOrCreate]: https://gorm.io/docs/advanced_query.html#FirstOrCreate
// [FirstOrInit]: https://gorm.io/docs/advanced_query.html#FirstOrInit
func (db *DB) Attrs(attrs ...interface{}) (tx *DB) {
	tx = db.getInstance()
	tx.Statement.attrs = attrs
	return
}

    **FastAPI** provides the same `starlette.status` as `fastapi.status` just as a convenience for you, the developer. But it comes directly from Starlette.

## Changing the default

    enableTracing: true
    # This is the ingress service name, update if you used a different name
    ingressService: istio-ingress
    connectTimeout: 1s
    defaultConfig:
      ### ADVANCED SETTINGS #############
      # Where should envoy's configuration be stored in the istio-proxy container
      configPath: "/etc/istio/proxy"
      binaryPath: "/usr/local/bin/envoy"
