Oh this is interesting.

In my minimal test it works just fine and properly closes the connection.

In the full test, the connection is sent keep-alive on the response.

Same directory, all other headers are the same, being sent and being received, except for the keep alive

Both are php programs emulating a gif image.

Clearly I need to investigate more.

Just discovered if I call the main program with the full index.php name the connection is properly closed.

But if called just by the sub-directory ending in / it does a keep-alive

I would guess there is a lower rewrite rule that is causing havoc.

Why should a rewrite rule unset the connection: close though?
