Application Initialization requests-iis logs


  • We have many different applications deployed on a single server and the modularity of our overall solution often relies on usage of a few of these applications being called which reference one another (possibly different references depending on configuration/environment). we are noticing a bit of a delay in the first attempt to each of these .ashx requests so we are now to set up <applicationinitialization within each of the applications. After following the documentation on the set up of the <applicationinitialization section of the first application, I am now trying to discern if the delays are still present.  My means of determining this are usually the iis logs themselves (and the time-taken column specifically) however I never see any requests for any pages/handlers during application initialization/app pool restart timeframe. How can I tell if my application initialization setup is working?  Shouldn't I see these requests in iis logs when I restart the app pool/iis? The times I get in the time-taken field are a little inconsistent here and make it hard to discern. Because of this inconsistency id likely have to run a large number of tests and determine averages over these but I don't really have that kind of time.
