The first thing you ll notice is that this diagram is virtually identical to the state server diagram discussed earlier, and it turns out that the basic model and benefits are indeed consistent with that approach. The application gains scalability and fault tolerance because you can implement a web farm, whereby the web server that s handling each page request retrieves state from the central database.

Again, make a small change to the Java class:

The collection classes in the SystemCollectionsGeneric namespace are designed to be convenient, but they are not suitable for using with Tasks However, the collection classes in the SystemCollectionsConcurrent namespace are designed to work with Tasks, although they are not particularly convenient to use The concurrent collection classes use sophisticated synchronization techniques to avoid race conditions without incurring the performance problems that critical regions incur Table 25-5 describes the most useful concurrent collection classes..
