跨 Web api 请求（用户会话）共享和更新静态集合

Question

I need each user requestid to store in static collection object. on each next request need to check if same user request exist then process some specific task using it.

So, to achieve this, I am thinking to preserve static list object. but as in web requests it will not give me correct value or update collection correctly because of static object in web.

can you please share me what is the ideal approach here, I should use or way to handle static collection object in web (while updating collection or retrieving collection).

If you want to build it yourself then at least use a concurrent collection:http://msdn.microsoft.com/en-us/library/dd997373(v=vs.110).aspx since you will be accessing the collection from multiple threads.

Otherwise I suggest using MemoryCache, a thread-safe built-in mechanism. See http://msdn.microsoft.com/en-us/library/ff477235.aspx
