Help with WiFi 101 tutorial

Hardware MKR Family MKR1000

I'm following along with MKR1000 WiFi Robot | Arduino Project Hub

I've made a few modifications in order to control some motors through the MKR Motor Carrier board. I noticed that when you click a button the browser will connect twice. Here is the log:

new client //THE BROWSER FIRST CONNECTS HERE

I must be missing something about how browsers interact with websites, but why it is doing this is beyond me.

Any help at all would be so appreciated!!

Thanks!

Hi @malk0lm,

Your browser is sending a HTTP GET request for /favicon.ico:

GET /favicon.ico HTTP/1.1

I suggest you change the sketch to filter out the path in the GET request.
