Varnish VS cloudscraper

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 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.

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).

Try https://github.com/yifeikong/curl_cffi or https://github.com/VeNoMouS/cloudscraper , I believe you should be able to bypass this.

But scraping has definitely gotten tougher with services like cloudflare that even the popular cloudscraper gave up years ago and never made a comeback.

If you're scraping with Python, try cloudscraper—among other things(!), it supports JS rendering (basically the bare-minimum check cloudflare does), without needing to run a full browser in the background. It's built on requests, so integration (for me, anyway) was pretty easy.

I've tried using Cloudscraper here https://github.com/VeNoMouS/cloudscraper but I get the following error:

No amount of googling turns up anything. There are others with the same problem - but no real solution. In the gitlab README it explains that to solve CAPTCHAs with cloudscraper you need an API key, which would explain the error that it's not available in the free version. But for the life of me, I can't find where to get a key or any other solution.

Anyone with a stake in bypassing anti-bot measures isn't going to share their tactics, since sharing it will lead to such workaround being patched or mitigated, requiring them to research for more bot detection workarounds.

Projects like cloudscraper[0] are often linked to point and say "look! they broke Cloudflare!" but CF and the rest of the industry has detections for tools like this, and instead of rolling out blocks for these tools, they give website owners tools like bot score[1] to manage their own risk level on a per-page basis.
