Static caches in web services

Is this the right way to initialize a static cache object in a web service?

public class someclass{
 private static Cache cache;
 static someclass()
    {
        cache = HttpContext.Current.Cache;
    }
}

More Info:

Seems like I receive more then one cache object from webservice. It creates a new request that only lasts for the duration of that call. If I move to a different machine, it creates a new request (and I think a webservice ) object that returns new cache. (because I can see two different caches being returned in the sniffer) By forcing it to be static I was hoping to have only one. However no avail. doesn't work.

From stackoverflow

• This looks good to me - especially if you are going to wrap the Current.Context and expose properties for cache values like this:

  public static class CacheManager
  {
      public static Boolean Foo
      {
          get { return (Boolean)HttpContext.Current.Cache["Foo"] }
          set { HttpContext.Current.Cache["Foo"] = value; }
      }
  
      // etc...
  }
  

  You don't really need to create a private reference to the current cache unless you are only doing so to save on typing. Also notice that I made the class static as well.

• Why not just access it directly using HTTPContext.Current.Cache?

  RichardOD : Then there is something wrong with your machine. Are you specifying timeout values for the items in cache? Does your machine have only a small amount of RAM?
