Answer 1

Your co workers are right, if one thread locks a resource and another thread attempts to use it then your thread pool goes boom! Not very good outcome. Most people resolve this by creating new objects and passing them into paramaterized threads. If you absolutely need to use the same object then you must implement some code that first checks to see if the resource is being used by another thread and then waits a little while before checking again. An example would be to create a IsInUse bool that you always check first, then your thread sets it to true if it is using that resource, then false when it is done, preventing other threads from attempting to use the underlying resource (your httpContext). I hope this helps.
