[stephentoub]

@geoffkizer, it looks like this test has now failed several times since it was modified in dotnet/corefx#27266. Mind taking a look?

[geoffkizer]

My best guess is that the Connection: close I added is confusing things.

[geoffkizer]

Unfortunately it's not trivial to just take out the Connection: close logic.

I'm tempted to just revert the test additions I made, and file a separate issue to improve the tests. That's probably the best way to make this reliable again in the short term.

[geoffkizer]

Let me try something simple that might fix it. If not, I'll need to do something more involved.

Yeah, I'll need to dig into this in more detail.

I think for now I'll just back out the test change.
