The test runs several downloads and then immediately runs a number of
POSTs for the upload evaluation...

I have not adjusted the time stamps of the headers above. As you can
see, there is a 5 second difference between when the speedtest server
responds to the last download test request, and when it responds to the
first upload test. My proxy is set explicitly in my browser.

Could it be related to interception?
