considerations when recycling applications

when applications recycled, possible session state lost. during overlapped recycle, occurrence of multi-instancing possibility.

loss of session state: many iis applications depend on ability store state. iis 6.0 can cause state lost if automatically shuts down worker process has timed out due idle processing, or if restarts worker process during recycling.

occurrence of multi-instancing: in multi-instancing, 2 or more instances of process run simultaneously. depending on how application pool configured, possible multiple instances of worker process run, each possibly loading , running same application code. occurrence of overlapped recycle example of multi-instancing, web garden in 2 or more processes serve application pool regardless of recycling settings.

if application cannot run in multi-instance environment, must configure 1 worker process application pool (which default value), , disable overlapped recycling feature if application pool recycling being used.
