Caution when stopping and starting an IIS application pool with appcmd

2010-05-12T04:24:00Z

When starting and stopping IIS 7 application pools from command line with appcmd.exe, you should be aware of a behavior that can sometimes lead to unintended circumstances. To explain it, lets first review what happens when you stop an application pool with the InetMgr.exe tool: 1) Set the autoStart property of the <applicationPool> configuration element to false . This causes WAS to not start any worker processes when a new request to an application mapped to the application pool arrives....(read more)

Troubleshooting performance counter problems with PerfMon and a debugger

2009-05-24T04:17:00Z

Performance counters are a wonderful tool when it comes to quickly assessing system health and performance of Windows subsystems. In addition to learning much about the operation of Microsoft products, exposing performance counters from your own code can be extremely valuable for the very same reasons. We do this a lot for LeanServer code – and it saves a lot of time and money when it comes to monitoring, diagnostics, and performance analysis in production. As with many things, performance...(read more)

Be a part of the energy revolution / Help Save Kilowatt Ours

2009-05-21T17:44:00Z

I dont usually post activist stuff on the blog, but I have to make an exception in this case. A year ago, I caught a late night showing of Jeff Barrie's Killowatt Ours, a 1 hour long film about the true impact of energy production on our environment, our health, and the extent to which we can help meet our growing energy demands by simply reducing our energy footprint. Lets just say the film was eye-opening, even given the fact that I've been in the energy field in one way or another for...(read more)

Workaround for using IIS 7 url authorization with ASP.NET roles

2009-05-12T03:33:00Z

When using the IIS 7.0 Integrated pipeline, you gain access to a ton of cool scenarios where IIS and ASP.NET features work together to provide value for your application – regardless of the application content. Most of these features involve using ASP.NET features (e.g.Forms Authentication) to provide their services for non-ASP.NET content. These have been at the core of most of the demos we did while developing the Integrated pipeline, and consequently are the most well known. The other major...(read more)
