Sharepoint Excel Services Recycling the App Pool

I have a question regarding sharepoint excel web services session handling. What happens if we recycle the app pool. If an application has opened an excel workbook programmatically using excel web services, would restarting the app pool or re-setting the开发者_运维知识库 IIS have any affect.

Thanking you in anticipation!

If you restart the app pool the session stored in memory in Excel Services backend will no longer exist and therefore any request against that session will fail.
