    distribyted

    distribyted

    Torrent client with HTTP, fuse, and WebDAV interfaces

    Distribyted is an alternative torrent client. It can expose torrent files as a standard FUSE mount or webDAV endpoint and download them on demand, allowing random reads using a fixed amount of disk space. Distribyted supports several ways to expose the files to the user or external applications. Applications that supports WebDAV can access torrent files using this protocol. It is recommended when distribyted is running in a remote machine or using docker. Distribyted can show some kind of files directly as folders, making it possible for applications to read only the parts that they need. Here is a list of supported, to-be-supported, and not supported formats. Play multimedia files on your favorite video or audio player. These files will be downloaded on demand and only the needed parts.

    Feign

    Make writing Java http clients easier

    Feign is a Java to HTTP client binder that was built primarily to make writing Java http clients easier. Inspired by previous projects Retrofit, JAXRS-2.0 and WebSocket, Feign was designed to reduce the complexity that is often involved in binding the Denominator uniformly to HTTP APIs, no matter the ReSTfulness. Feign works by processing annotations into a templatized request, to which arguments are applied in a straightforward manner before output. While it may only support text-based APIs, it simplifies system aspects dramatically and makes it much easier to unit test your conversions. Feign makes use of great tools like Jersey and CXF for writing Java clients for ReST or SOAP services. It also lets you write your own code on top of http libraries, and connects your code to http APIs with little overhead.

    Sōzu

    Sōzu

    Sōzu HTTP reverse proxy, configurable at runtime, fast and safe

    Open source HTTP reverse proxy built in Rust for immutable infrastructures. Most existing tools have a static vision of production: a service is installed once on a long-lived server, updated from time to time, with configuration rarely changing. There's now a shift in infrastructure to short-lived virtual machines and hundreds of new deployments per day, and the usual tools reach their limits. How do we reconcile a dynamic environment with availability guarantees? How can we get "zero downtime" deployments for critical services? SŌZU is a HTTP reverse proxy built in Rust, that can handle fine-grained configuration changes at runtime without reloads, and is designed to never ever stop. SŌZU receives and handles configuration changes at runtime and updates its internal configuration without restarts. You can update the configuration multiple times per second, and it will take care of lingering connections.

    r2

    r2

    HTTP client, spiritual successor to request

    Early in Node.js I wrote an HTTP client library called request. It evolved along with Node.js and eventually became very widely depended upon. A lot has changed since 2010 and I've decided to re-think what a simple HTTP client library should look like. This new library, r2, is a completely new approach from request. Rather than being built on top of the Node.js Core HTTP library and shimmed for the browser, r2 is built on top of the browser's Fetch API and shimmed for Node.js. APIs are meant to be used with async/await, which means they are based on promises. Being written to the Fetch API is a huge benefit for browser users. When running through browserify request is ~2M uncompressed and ~500K compressed. r2 is only 66K uncompressed and 16K compressed.

    Interactsh

    Interactsh

    An OOB interaction gathering server and client library

    Interactsh is an open-source tool for detecting out-of-band interactions. It is a tool designed to detect vulnerabilities that cause external interactions. Interactsh Cli client requires go1.17+ to install successfully. interactsh-client with -sf, -session-file flag can be used store/read the current session information from user defined file which is useful to resume the same session to poll the interactions even after the client gets stopped or closed. Running the interactsh-client in verbose mode (v) to see the whole request and response, along with an output file to analyze afterwards. Using the server flag, interactsh-client can be configured to connect with a self-hosted Interactsh server, this flag accepts single or multiple server separated by comma. Default servers are subject to change/rotate/down at any time, thus we recommend using a self-hosted interactsh server if you are experiencing issues with the default server.

This allows you to utilize other PSR-7 compatible libraries with Guzzle. Abstracts away the underlying HTTP transport, allowing you to write environment and transport agnostic code; i.e., no hard dependency on cURL, PHP streams, sockets, or non-blocking event loops. Middleware system allows you to augment and compose client behavior.

    HttpClient component

    HttpClient component

    Provides powerful methods to fetch HTTP resources synchronously

    Provides powerful methods to fetch HTTP resources synchronously or asynchronously. The HttpClient component is a low-level HTTP client with support for both PHP stream wrappers and cURL. It provides utilities to consume APIs and supports synchronous and asynchronous operations. The HTTP client contains many options you might need to take full control of the way the request is performed, including DNS pre-resolution, SSL parameters, public key pinning, etc. They can be defined globally in the configuration (to apply it to all requests) and to each request (which overrides any global configuration). It's common that some of the HTTP client options depend on the URL of the request (e.g. you must set some headers when making requests to GitHub API but not for other hosts). If that's your case, the component provides scoped clients (using ScopingHttpClient) to autoconfigure the HTTP client based on the requested URL.
