Scope: What This Course Builds On, and Why It's IIS-Only

Web Servers Fundamentals compared Apache, Nginx, and IIS across architecture, configuration philosophy, virtual hosting, TLS, and performance — but deliberately kept its own IIS material introductory in several specific places. This course exists to go deep on exactly those places, with one deliberate exception named honestly up front, rather than forced into matching its siblings' shape.

What Web Servers Fundamentals Already Covered

IIS shows up in exactly as many of that course's chapters as Apache did — seven — genuinely more than Nginx's three, and for a similar underlying reason: like Apache's .htaccess, IIS has its own real per-directory override mechanism (web.config), which Web Servers Fundamentals Chapter 3 found structurally closer to Apache's own philosophy than to Nginx's centralized one. Chapter 2 introduced Application Pools and their w3wp.exe worker process conceptually, including scheduled/threshold-based recycling, without configuring either in depth. Chapter 3 introduced the GUI/XML configuration model — applicationHost.config machine-wide, web.config per-directory — without covering real inheritance behavior. Chapter 4 covered Sites and bindings at a basic level. Chapter 6 named Application Request Routing (ARR) as IIS's own reverse-proxy capability — genuinely an add-on module, not built in the way Apache's mod_proxy or Nginx's proxy_pass are. Chapter 7 covered the Windows Certificate Store and HTTPS bindings generically. Chapter 8 named IP/Domain Restrictions and Basic/Windows Authentication without real directive depth. Chapter 9 named Dynamic/Static Content Compression and Output Caching, briefly and comparatively.

Why This Course Is IIS-Only

The comparative question — Apache vs. Nginx vs. IIS, and which one actually fits a given job — already belongs to Web Servers Fundamentals, and its own capstone decision framework is the right place to answer it. This course assumes that question is already settled: either IIS is genuinely the right fit for the job in front of you (very often because the application itself is a Windows/.NET one), or you simply want to understand IIS itself in real depth. Either way, every chapter from this point on is IIS configuration and IIS-specific behavior — no more comparing.

A Deliberate Scope Boundary: No Dedicated Reverse-Proxy Chapter

Both Apache In Depth and Nginx In Depth devote real chapters to reverse proxying and load balancing, because mod_proxy and proxy_pass are core, built-in capabilities of those two servers. IIS's own ARR module is a genuinely optional add-on most IIS installations never install at all — IIS's primary job in the overwhelming majority of real deployments is hosting ASP.NET/.NET applications directly, not proxying to something else. Giving ARR its own full chapter here would misrepresent how central it actually is to IIS, compared to how central reverse proxying genuinely is to Apache and Nginx. This course goes deep on what IIS itself does natively instead.

What This Course Actually Adds

• Chapter 2 — Application Pool identities, real recycling triggers, and live health monitoring, not just the conceptual overview
• Chapter 3 — web.config/applicationHost.config inheritance in real depth
• Chapter 4 — the Integrated Pipeline, and Managed vs. Native modules — a genuinely new topic Fundamentals never touched at all
• Chapter 5 — Sites, virtual directories, and application boundaries in depth
• Chapter 6 — the URL Rewrite module in depth (distinct from ARR — Rewrite alone, without ARR, is genuinely common and doesn't require proxying anything)
• Chapter 7 — HTTPS bindings, SNI, and the centralized certificate store, well beyond Chapter 7's generic treatment
• Chapter 8 — Windows Authentication, Request Filtering, and IP restrictions with real directive depth
• Chapter 9 — performance tuning, logging, and Failed Request Tracing — another genuinely new topic
• Chapter 10 — a capstone that designs and hardens one complete, production-shaped IIS deployment
