Nginx stalled cache updating

This mode of operation can be very inefficient, particularly for complex web pages with a large number of elements or when network links are slow.Creating a new TCP connection requires a ‘three‑way handshake’, and tearing it down also involves a two‑way shutdown procedure.A basic understanding of the NGINX architecture and configuration concepts is assumed.This post does not attempt to duplicate the NGINX documentation, but provides an overview of the various options and links to the relevant documentation.In the late 1990s, a developer named Grisha Trubetskoy came up with an Apache module called mod_python to execute arbitrary Python code.For several years in the late 1990s and early 2000s, Apache configured with mod_python ran most Python web applications.To learn how NGINX can improve speed and scalability of your applications, read our blog post Tuning NGINX for Performance for a breakdown of configurations. If you’ve not done so before, take a look at the output from an HTTP debugging tool such as the one in your web browser, and check out the standard request and response structure: In its simplest implementation, an HTTP client creates a new TCP connection to the destination server, writes the request, and receives the response.

In this blog post, we’ll investigate how HTTP operates and how common HTTP servers process HTTP transactions.

Therefore the Python community came up with WSGI as a standard interface that modules and containers could implement.

WSGI is now the accepted approach for running Python web applications.

NGINX is well known as a high‑performance load balancer, cache, and web server, powering over 40% of the busiest websites in the world.

For most use cases, default NGINX and Linux settings work well, but achieving optimal performance sometimes requires a bit of tuning.
