Will a request in IIS run on a single thread?

Question

We have a system that runs in IIS.

The system should always run using the same \"culture\", but we cannot rely on the server settings being set correct.

Answer 1

If you know you want the culture to stay the same for all threads, then that should be a fine approach.

However, if you need to set the culture on, say, a per-request basis that may be different from one request to the next, that can potentially not be a reliable approach. Under high load, we have seen threads reused for multiple requests and requests migrated from one thread to another, leaving their culture (and other threadstatic info) behind.
