"Keep alive" is always used for HTTP 1.1, but it shouldn't cause you any

The server will tell the client how many bytes to expect. The client
downloads the data and counts the amount received.

When the connection is closed, the client can easily see if the two different
amounts differ. And then it says this.

No. And you'll see that you won't get this problem when you try this on more
servers. I just did and I can't make it fail...
