问题
We using ASP.NET 3.5 (Controls-based approach) and need to have storage specific for one http request only.
Thread-specific cache with keys from session id won't work because threads are supposed to be pooled and therefore I have a chance to have data from some previous request in cache, which is undesirable in my case. I always need to have brand new storage for each request available through whole request.
Any ideas how to do it in ASP.NET 3.5?
回答1:
We have used HttpContext.Current.Items collection to do RequestScope caching. It works well.
回答2:
just to clarify what ggonsalv was referring to
http://msdn.microsoft.com/en-us/library/system.web.httpcontext.items.aspx
HttpContext.Items["key"] = value;
UPDATE: the mvc specific version
http://msdn.microsoft.com/en-us/library/system.web.mvc.controller.httpcontext(v=VS.100).aspx

How about using the Context collection. This allows data to be shared between all your controls but only lasts for the request.
Use it like this context.Items("base_url") = "default.aspx"
