HTTP Desync Attacks: Request Smuggling Reborn | Blog - PortSwigger
HTTP requests are traditionally viewed as isolated, standalone entities. In this paper, I'll explore forgotten techniques for remote, unauthenticated attackers to smash through this isolation and splice their requests into others, through which I was able to play puppeteer with the web infrastructure of numerous commercial and military systems, rain exploits on their visitors, and harvest over $70k in bug bounties.

august 2019 by whip_lash — A modern request bin to collect, inspect and debug HTTP requests and webhooks gives you a URL that collects requests you send it so you can inspect them in a human-friendly way.

Use to see what your HTTP client is sending or to inspect and debug webhook requests.

WiFi (WiFi network summary, Detecting beacon, deauth floods etc.)
HTTP (Listing all visited websites, downloaded files)
HTTPS (Listing all websites opened on HTTPS)
ARP (MAC-IP table, Detect MAC spoofing and ARP poisoning)

CGIProxy-- HTTP/FTP Proxy in a CGI Script
This CGI script (or other) acts as an HTTP, HTTPS, or FTP proxy. Through it, you can retrieve any resource that is accessible from the server it runs on. This is useful when your own access is limited, but you can reach a server that in turn can reach others that you can't. In addition, the user is kept as anonymous as possible from any servers. Common uses include: anonymous proxies, other personal uses, VPN-like functionality, and others. It's very simple to install, and very configurable.

The headers we don't want
HTTP headers are an important way of controlling how caches and browsers process your web content. But many are used incorrectly or pointlessly, which adds overhead at a critical time in the loading of your page, and may not work as you intended. In this first of a series of posts about header best practice, we’ll look at unnecessary headers.

mitmproxy - an interactive HTTPS proxy
mitmproxy is your swiss-army knife for debugging, testing, privacy measurements, and penetration testing. It can be used to intercept, inspect, modify and replay web traffic such as HTTP/1, HTTP/2, WebSockets, or any other SSL/TLS-protected protocols. You can prettify and decode a variety of message types ranging from HTML to Protobuf, intercept specific messages on-the-fly, modify them before they reach their destination, and replay them to a client or server later on.

Internet protocols are changing | APNIC Blog
Now, significant changes to the core Internet protocols are underway. While they are intended to be compatible with the Internet at large (since they won’t get adoption otherwise), they might be disruptive to those who have taken liberties with undocumented aspects of protocols or made an assumption that things won’t change.

It's useful for testing how your own scripts deal with varying responses.

Just add the status code you want to the URL, like this:
