Using MySql with VB.NET

Visual Basic and MySql

Every now and then when I have a sudden burst of programming inspiration I reach inside my programming toolbox and pull out an old trusty friend – Visual Basic. Over the years I’ve appreciated the benefits of using VB. One of them is not having to spend countless days creating a Windows GUI application the old fashioned way by using C/C++. WndProc, GetMessage, and RegisterClass are things I used to do a decade ago as a Windows developer and it was a real pain.

With HTTP 2, No Need To Domain Shard

HTTP 2 Domain Sharding

Limited persistent connections.

Back in the days when HTTP 1.1 came out, the RFC 2616 specification said in section 8.1.4 entitled “Practical Considerations” that a user agent can only have two maximum connections to a domain at any point in your life.

Clients that use persistent connections SHOULD limit the number of simultaneous connections that they maintain to a given server. A single-user client SHOULD NOT maintain more than 2 connections with any server or proxy.

What this meant was that your browser should not have more than two HTTP connections open to a single domain. But this wasn’t really practical. The reason being, web pages were and still are very complicated in nature. If you open up and look at the HTML source of most web pages today, you are going to see a whole lot of HTTP references to images, Javascript, CSS, and other hypermedia types.
