One thing to watch for using the HttpContext.Current.Cache is that there is an overhead as the dictionary populates and depending on the amount of items in your cache that alone can become expensive. You may be better off using something else like Lucene.Net which can store its index in RAM, or even a static List<string> that gets repopulated on app recycle.

| Mar 13, 2012 at 8:48 | comment | added | Lars-Erik | Ah, bummer. Embarrasing. Anyway, the part about modification should still hold true. | |
| Mar 12, 2012 at 9:35 | comment | added | Guffa | @Lars-Erik: You read the specification wrong. The fact that static members of the class (all zero of them) are thread safe doesn't mean that a static variable holding an instance of the class is thread safe. Neither the variable nor the class instance is thread safe. | |

| Mar 8, 2012 at 13:07 | comment | added | Lars-Erik | A public static List<T> is threadsafe. Instance members are not guaranteed to be. But either way, as long as the collection is not modified during runtime, it does not matter. msdn.microsoft.com/en-us/library/6sh2ey19.aspx (see Thread Safety near bottom above Community Content) | |

Not sure I'm too keen on the recursion there, even if it should only be a single loop-around. I'd replace return GetProducts(); with the (also-repeat, might want to DRY it out) cached = HttpContext.Current.Cache["MyApp-Products"];.

Were you aware that the List<T> type that you are using as backend is not thread safe? You should really take that into account when attempting to use it in a multi-threaded environment such as ASP.NET.
