I'm new to SignalR and using it on my project. There is something I don't understand. Maybe it's my coding mistake or maybe it's how SignalR works behind the scene. I have an ASP.Net Core Hub that is hosted on Azure and My javascript client uses it for sending real-time messages between my users.
Everything works just fine except when I check my network tab, almost every 5-10 seconds, a POST request sending to the API even tho the client was already connected to the hub. Is this a default behavior or did I code something wrong?
Please see the screenshot below.
