## Build without `MsgPack` rendering feature
Gin enables `MsgPack` rendering feature by default. But you can disable this feature by specifying `nomsgpack` build tag.
```sh
$ go build -tags=nomsgpack .
```
This is useful to reduce the binary size of executable files. See the [detail information](https://github.com/gin-gonic/gin/pull/1852).

## Don't trust all proxies
Gin lets you specify which headers to hold the real client IP (if any),
as well as specifying which proxies (or direct clients) you trust to
specify one of these headers.
Use function `SetTrustedProxies()` on your `gin.Engine` to specify network addresses
or network CIDRs from where clients which their request headers related to client
IP can be trusted. They can be IPv4 addresses, IPv4 CIDRs, IPv6 addresses or
IPv6 CIDRs.
**Attention:** Gin trust all proxies by default if you don't specify a trusted
proxy using the function above, **this is NOT safe**. At the same time, if you don't
use any proxy, you can disable this feature by using `Engine.SetTrustedProxies(nil)`,
then `Context.ClientIP()` will return the remote address directly to avoid some
unnecessary computation.
```go
import (
"fmt"
"github.com/gin-gonic/gin"
)
func main() {
router := gin.Default()
router.SetTrustedProxies([]string{"192.168.1.2"})
router.GET("/", func(c *gin.Context) {
// If the client is 192.168.1.2, use the X-Forwarded-For
// header to deduce the original client IP from the trust-
// worthy parts of that header.
// Otherwise, simply return the direct client IP
fmt.Printf("ClientIP: %s\n", c.ClientIP())
})
router.Run()
}
```
**Notice:** If you are using a CDN service, you can set the `Engine.TrustedPlatform`
to skip TrustedProxies check, it has a higher priority than TrustedProxies.
Look at the example below:
```go
import (
"fmt"
"github.com/gin-gonic/gin"
)
func main() {
router := gin.Default()
// Use predefined header gin.PlatformXXX
router.TrustedPlatform = gin.PlatformGoogleAppEngine
// Or set your own trusted request header for another trusted proxy service
// Don't set it to any suspect request header, it's unsafe
router.TrustedPlatform = "X-CDN-IP"
router.GET("/", func(c *gin.Context) {
// If you set TrustedPlatform, ClientIP() will resolve the
// corresponding header and return IP directly
fmt.Printf("ClientIP: %s\n", c.ClientIP())
})
router.Run()
}
```
