To add a header, add the add_header declaration to either the location block or the server block: server { add_header X-server-header “my server header content!”; location /specific-location { add_header X-location-header “my specific-location header content!”; } } An add_header declaration within a location block will override the same add_header declaration in the outer server block. e.g. … Read more
Maybe you’re not doing it as root? Try sudo nginx -s reload, if it still doesn’t work, you might want to try sudo pkill -HUP nginx.
I have the following nginx virtual host (static content) for local development work to disable all browser caching: server { listen 8080; server_name localhost; location / { root /your/site/public; index index.html; # kill cache add_header Last-Modified $date_gmt; add_header Cache-Control ‘no-store, no-cache’; if_modified_since off; expires off; etag off; } } No cache headers sent: $ curl … Read more
You can tell Gunicorn to reload gracefully using the HUP signal like so: kill -HUP <pid> (see the FAQ for details) I use Supervisor to control my Gunicorn server, which allows me to use this (slightly hacky) way of reloading Gunicorn after a deploy: supervisorctl status gunicorn | sed “s/.*[pid ]\([0-9]\+\)\,.*/\1/” | xargs kill -HUP … Read more
Uploading files is actually possible with AJAX these days. Yes, AJAX, not some crappy AJAX wannabes like swf or java. This example might help you out: https://webblocks.nl/tests/ajax/file-drag-drop.html (It also includes the drag/drop interface but that’s easily ignored.) Basically what it comes down to is this: <input id=”files” type=”file” /> <script> document.getElementById(‘files’).addEventListener(‘change’, function(e) { var file … Read more

If you would like to permanently alter the settings you can edit /etc/sysconfig/selinux If SELinux is your problem you … Read more
When you “run Flask” you are actually running Werkzeug’s development WSGI server, and passing your Flask app as the WSGI callable. The development server is not intended for use in production. It is not designed to be particularly efficient, stable, or secure. It does not support all the possible features of a HTTP server. Replace … Read more
In general, the biggest immediate benefit of HTTP/2 is the speed increase offered by multiplexing for the browser connections which are often hampered by high latency (i.e. slow round trip speed). These also reduce the need (and expense) of multiple connections which is a work around to try to achieve similar performance benefits in HTTP/1.1. … Read more
It’s just what the error says – Request Header Or Cookie Too Large. One of your headers is really big, and nginx is rejecting it. You’re on the right track with large_client_header_buffers. If you check the docs, you’ll find it’s only valid in http or server contexts. Bump it up to a server block and … Read more
Edit November 2014: the initial answer is not correct and is incomplete ; it needed a refresh! here it is. Basically, there are two cases You own a wildcard certificate (or multi-domains certificate) In this case, you may use several vhosts listening to the same IP address/https port, and both vhosts use the same certificate … Read more
