Stop Regenerating Data Protection Keys on Every Recycle
App pool recycles that wipe in-memory Data Protection keys log everyone out. Persist the key ring outside the publish folder so cookies and antiforgery survive IIS restarts.

Folder Swap Cutover for .NET 10 on IIS
Shared and VPS IIS hosts rarely offer Azure-style slots. Publish to a sibling folder, smoke-test it, then flip the site physical path for a clean cutover.

Parameter Sniffing Fixes for ASP.NET SQL Workloads
One cached plan can make the same ASP.NET query fly or crawl. Spot parameter sniffing on SQL Server and fix it without blanket recompiles.
-
Output Cache for ASP.NET Core 10 APIs on IIS
Cut repeat SQL and CPU on IIS-hosted APIs with ASP.NET Core output cache. Wire policies, vary-by rules, and tag eviction so responses stay fast and correct after recycles.

IIS App Pool Recycling Without Dropping ASP.NET Requests
Default IIS recycles hit at awkward hours and can cut in-flight work. Schedule quiet-hour recycles, enable overlap, and set shutdown limits so ASP.NET finishes cleanly.

GitHub Actions Web Deploy for .NET 10 on IIS
Wire publish and Web Deploy into GitHub Actions so ASP.NET Core 10 hits IIS the same way every push. Covers profiles, safe excludes, and a post-deploy smoke check.

SQL Connection Pools and Timeouts on IIS Hosts
Pool exhaustion often surfaces as random SQL timeouts under load. Tune Max Pool Size, Connect Timeout, and CommandTimeout for ASP.NET apps on IIS before traffic spikes.
-
Tune .NET GC for ASP.NET Core App Pools on IIS
Default GC settings can thrash IIS app pools under load. Align heap limits with recycle thresholds so ASP.NET Core 10 stays stable on Windows hosts.
-
Security Headers for ASP.NET Core 10 on IIS
Missing response headers still open clickjacking and MIME sniff paths on hosted ASP.NET sites. Wire HSTS, CSP, and cookie flags once in middleware or web.config.

IIS URL Rewrite HTTPS Redirects Without Loops
Force HTTPS and a single host name at the IIS edge without redirect loops. Patterns that play cleanly with ASP.NET Core in-process hosting.
