IIS 7.5 : Configuring concurrent requests

Hi,

I have hosted a ASP.NET 4.0 application in IIS 7.5. My application uses a legacy component that is not thread safe. So I want IIS to process only one request at a time i.e. no concurrent requests. How can I achieve this?

Search through MSDN says that we can use maxConcurrentRequestsPerCPU, but even if I set this to 1, it will be per CPU rather than for the whole worker process (application pool).

Any help would be highly appreciated.

Regards,

Rajiv
