Subject: Re: [users@httpd] Apache HTTP2 and benchmarking with h2load
archived-at: Thu, 25 Aug 2016 13:06:46 -0000

If you add something like

    LogLevel http2:debug
    LogLevel ssl:debug
    LogLevel core:debug

you should find information about negotiation in your error.log. Strange
that Firefox works and h2load does not. I use the later regularly in my =
tests.

Looking forward to see some log output...

I'm guessing that it is not a problem on the h2load side.
