Here is `META`
{{{
uwsgi.node = 'myhostname'
SERVER_NAME = 'myhostname'
HTTP_HOST = 'myhostname'
}}}
I am using jQuery to do a lot (1000x) of requests to load historical data.
sometimes the requests fail miserably when they shouldn't
`server_name` is set correctly in the nginx.conf (less than 1% of the
requests fail).
{{{
bash-4.1$ uwsgi --version
2.0.6
}}}
here is the uwsgi.ini
{{{
