title: Golang Increment data to Redis
body: <p>I have been playing around with golang and redis.  I just stood up a simple http server and wanted to increment requests on redis.  I am blowing up the connections (I think).  I found that with redigo you can use connection pooling, but not sure how to implment that in go when I am serving the requests (where do you instantiate / call the pool from). </p>
  
  <p>error: can't assign requested address. </p>
  
  <p>Any suggestions would be appreciated....I am sure I am incorrectly making the connections, but just not sure how to change. </p>
  
  <p><strong>EDIT: Modified per pauljz's suggestions -- Works great now</strong></p>
  
  <pre><code>    var pool redis.Pool
  
      func qryJson(rw http.ResponseWriter, req *http.Request){
  
          incrementRedis()
      }
  
      func incrementRedis () {
  
      t := time.Now().Format("2006-01-02 15:04:05")
      conn := pool.Get()
      defer conn.Close()
      if _, err := conn.Do("HINCRBY", "messages", t, 1); err != nil {
          log.Fatal(err)
  
      }
  
  
      }
  
  func main() {
      runtime.GOMAXPROCS(runtime.NumCPU())
      pool = redis.Pool{
              MaxIdle: 50,
              MaxActive: 500, // max number of connections
              Dial: func() (redis.Conn, error) {
                      c, err := redis.Dial("tcp", ":6379")
                      if err != nil {
                              panic(err.Error())
                      }
                      return c, err
              },
      } 
      http.HandleFunc("/testqry", qryJson)
      log.Fatal(http.ListenAndServe(":8082", nil))
  }
