# gin-limit

Limit the number of simultaneous HTTP connections with this Gin middleware. When the connection limit is reached, it refuses new connections and returns HTTP 503. 

## Example

```go

package main

import (

	"github.com/gin-gonic/gin"

	"github.com/umermansoor/gin-limit"

)

func main() {

  r := gin.Default()

  r.Use(limit.MaxConnections(15))

  r.Run(":8080")

}

```
