Varnish VS Nginx

Varnish Cache is a tool that provides a caching HTTP reverse proxy in order to accelerate your web applications. Once Varnish Cache is installed in front of any server that understands HTTP and configured to cache the contents, delivery speeds are typically enhanced by a factor of 300-1000x, depending on architecture. Kilobyte22 finds this tool along with HAProxy to be a winning combo.

In this case, caching mechanism is situated in the proxy server or reverse proxy server like Nginx, Apache, or Varnish, and most probably it is a part of ISP (Internet Service Provider).

To handle this level of traffic, you can use tools such as Varnish HTTP Cache, which caches the information of a news article starting from the first user who accesses and makes the request. Once Varnish caches the page, subsequent users will receive a response that is saved in memory. This process allows you to avoid unnecessary synchronous requests and send a quick response to users.

A couple of dedicated server-side resource caching solutions have emerged over the years: Memcached, Varnish, Squid, etc. Other solutions are less focused on web resource caching and more generic, e.g., Redis or Hazelcast.

VARNISH

Edge Side Includes (ESI): a more modern alternative to SSI. ESI can handle variables, have conditionals, and supports better error handling. ESI is supported by caching HTTP servers such as Varnish.

For this objective, I am looking for willing volunteers to run through two phases of test deployments. These phases will each involve creating a scalable Varnish Cache cluster on Azure Kubernetes Service and answering a few questions about your experience. The deployments should take a total of around 30 min (or less) and will require the creation of a very minimal Kubernetes cluster. For some more information on Varnish Cache check out: https://varnish-cache.org/

For reads, caches are the primary tool, such as Varnish or memcached.

Others have pointed out some very valid issues. A quick hack, try using Varnish Cache (https://varnish-cache.org/), you can really accelerate the static content delivery.

Yeah, unless I'm looking at it wrong, there doesn't seem to be any meaningful difference between 1.25.5 and 1.26.0:

However, it's very unlikely that .NET developers will directly expose their Kestrel-based web apps to the internet. Typically, we use other popular web servers like Nginx, Traefik, and Caddy to act as a reverse-proxy in front of Kestrel for various reasons:

Have a look at:

https://github.com/nginx/nginx/blob/master/src/http/modules/...

It's got the whole checklist: nginx idiosyncratic module system, inline parsing, custom utf conversion, buffer preallocation and adjustments, linked lists, comments about side effects of custom allocator, and probably other things.

It's not easy to deal with source like that and any serious improvement to that area would effectively be a rewrite anyway.

Since anything doing work in nginx is a module anyway, it wouldn't even have to be a full rewrite in one go.

According to this article, nGinx is being used to serve 34% of all websites in the world. I checked out who's contributing to nGinx, and just like I thought, the project has 8,208 commits, and 5,366 of those commits was made by 2 software developers; igorsoev and mdounin.

Nginx + Roadrunner (fcgi mode)

Apache’s mod_fastcgi’s last commit was 2 weeks ago:

https://svn.apache.org/viewvc/httpd/httpd/trunk/

It’s a fork of what you linked (and was more popular afaik back when fastcgi was state of the art, and apache was the undisputed champion of web servers).

These days, nginx has more market share than apache, and its fastcgi module is one of the more recently updated ones in its source tree (5 months vs multiple years):

https://github.com/nginx/nginx/tree/master/src/http/modules

If I was going to build an embedded web server, I’d start with nostd rust, probably with though axum + tokio, since thats already memory safe-ish.

If I needed fastcgi for some reason (dynamically loadable endpoints, or os-level isolation), there are at least four implementations of fastcgi for it. No idea if any are decent though.

APISIX is an API Gateway. It builds upon OpenResty, a Lua layer built on top of the famous nginx reverse-proxy. APISIX adds abstractions to the mix, e.g., Route, Service, Upstream, and offers a plugin-based architecture.
