session can be operated based on the httpcontext.
The httpcontext class has a static property called current. We can use this property to obtain the current httpcontext. Of course, the irequiressessionstate interface should also be added to operate sessions in CS.
Methods and attributes related to sessions, requests, response, and server can be applied according to this mode and method.
For example, to obtain the IP address of the current visitor in the CS file of appcode, you can use httpcont

Before we discuss the differences between the two mechanisms in detail, we first need to understand the concurrency changes.
1. What is sync modification?
When one or more threads are traversing a collection collection, another thread modifies the contents of th
Java (Part 3 and 4) ----- fail-fast mechanism, java ----- fail-fast
In the JDK Collection, we often see something similar to this:
For example, ArrayList:
Note: The Fast failure behavior of the iterator cannot be guaranteed, because in general, it is impossible to make any hard guarantee for non-synchronous concurrent modifications. The quick failure iterator will do its best to throw ConcurrentModificati
One: Rapid failure (fail-fast)When traversing a collection object with an iterator, if the contents of the collection object are modified (added, deleted, modified) during traversal, the concurrent modification Exception is thrown.Principle: The iterator accesses the contents of the collection directly during traversal, and uses a Modcount variable during traversal. When a collection is traversed, the value of Modcount is changed if the content change
