If you want a plugin that supports request customization for REST, WebSocket, Socket.IO, SignalR, Server-Sent Events (and much more) out of the box, with regular updates and outstanding support from the developer, then BestHTTP is THE tool for you! You can visit the new demo page now: https://besthttpdemosite.azurewebsites.net/ Check out the docs. Supported platforms: WebGL iOS, Android Windows Store Apps/Windows 10/UWP Windows, Mac OS X, Linux ALL source code included! Most notable HTTP features are: Customize all parts of your requests: Methods(GET, HEAD, POST, PUT, DELETE, PATCH) Headers Cookies Max redirect count Timeouts Access all kind of data sent by the server: Headers Status code Cookies Connection pooling Connection and request timeouts Automatic Cookie handling Great range of Proxy support (Fiddler, Charles, etc.) Automatic caching, validating just like your browser Set your cache size and freshness gzip content encoding Basic and Digest authentication Multiple (url-encoded and multipart/form-data) form types Automatic redirection handling Upload and Download progress tracking Access your data while downloading You can resume downloads using Range headers HTTPS Customize a great range of global settings: Max connection per server Enable/disable cookies Private 'Browsing' Cookie Jar size etc WebSocket features: Full RFC compliance Support for extensions: Compression Extensions for WebSocket (RFC7692) Easy to use, 'just works' experience Socket.IO features: Compliance with the latest (1.x and 2.x) Socket.IO implementation Automatic transport upgrade/downgrade Binary data sending/receiving You can plug in your favorite Json decoder SignalR features: Works with the latest SignalR implementation Easy to use API Hubs Support for authentication Progress messages for long running jobs Automatic transport upgrade/downgrade You can plug in your favorite Json decoder SignalR Core features: Supports latest SignalR Core Strongly typed callbacks Uses the fastest Websocket transport Package includes a Header-based authenticator Server-Sent Events features: Compatible with the latest specification (http://www.w3.org/TR/eventsource/) Easy to use API Changelog: 1.12.4 (2019.07.30) Socket.IO [Bugfix] [Polling Transport] Fixed a bug where the received length is different from the byte-length of the packet and the plugin read and tried to parse the truncated packet. SignalR Core [Bugfix] All transport error during closing will be ignored now. Websocket [Bugfix] Fixed a NullReferenceException that occured when the send thread closed and other parts tried to use a disposed resource. 1.12.3 (2019.07.17) General [Bugfix] Fixed a bug where the HTTPCacheService would try to use non-supported recursive locking [Bugfix] WriteOnlyBufferedStream didn't call Flush on the underlying stream Websocket [Bugfix] Didn't use the created buffered stream 1.12.2 (2019.06.12) General [Improvement] When the same content is already stored on the disk, new responses will no write it again saving cpu and disk activity [Bugfix] Fixed compile errors for UWP [Bugfix] Fixed a possible NullReferenceException when the server sends back no headers at all [Bugfix] Read and store responses are in a write lock to avoid an error when two or more requests to the same uri are executed. [Bugfix] When CookieJar.Get called before any other CookieJar.Load it throwd an error 1.12.1 (2019.05.29) General [Bugfix] Callbacks didn't called when abort requested on a HTTPRequest [Bugfix] ReaderWriterLockSlim of the HTTPRequest is nulled out while it later tried to use it 1.12.0 (2019.05.28) General [Improvement] Part of a larger code rewrite/overhaul removed a lot of locks and added lock-free collections and/or using ReaderWriterLockSlim. These changes affect all parts of the plugin from cookies to the signalr core protocol.

This is quite a large change that touches all part of the plugin, but reduces the plugin's memory garbage production very very much! (Thanks to Teemu @ Delta Cygni Labs for the base idea and code donation!) [New Feature] All samples are available in a public git repo too (https://github.com/Benedicht/BestHTTP_Examples) [New Feature] Added a new IIOService interface and the plugin now uses the file system through this abstraction.
