Because of Thread Agility in ASP.Net, ThreadStatic is not an appropriate mechanism to use in web applications for segregating static property access from one request to the next.
In order to avoid lots of calls to HttpContext.Current.Items and the associated null checks and so forth, is there any trickery offered by the .Net framework whereby I could create an attribute which works sort of like ThreadStatic, but utilises HttpContext.Current.Items if the current code is being executed within an ASP.Net request context?
note: I am aware that ThreadStaticAttribute is a special case with no functional code internally and is checked for by the JIT compiler before any of its magic is worked.
