Deep Web: A Web Cmdlets Deep Dive
summary
Covers concrete behaviors and fixes: Invoke-WebRequest and Invoke-RestMethod now use System.Net.HttpClient (no IE DOM parsing), FTP/file URLs and SSL3 are gone, and TLS 1.2 works out of the box; a self hosted web listener (ASP NET Core Kestrel) runs 200+ Pester tests on ports 8083/8084 and demonstrates HTTPS and failures. Shows how to use skip certificate check and the session variable / cookie container, explains header array vs string differences, missing raw error bodies in Core, and why basic web scraping still only works on Windows PowerShell 5.1.
