When to use distributed cache for session management?
A consideration when choosing a distributed cache for session management is determining how many nodes may be needed in order to manage the user sessions. Generally speaking, this decision can be determined by how much traffic is expected and/or how much risk is acceptable.
Where does the caching take place in a server?
Server-side caching is done by the process that provides the business services that are running remotely. The most basic type of cache is an in-memory store. It’s held in the address space of a single process and accessed directly by the code that runs in that process.
When do you need to use caching in an application?
Caching can also be used to avoid repeating computations while the application is running. If an operation transforms data or performs a complicated calculation, it can save the results of the operation in the cache.
What does sticky session mean in web management?
Sticky sessions, also known as session affinity, allow you to route a site user to the particular web server that is managing that individual user’s session.
How are session identifiers sent back to the server?
Session identifiers can be sent back to the server via cookies, URL params, hidden form fields or a custom header. Additionally, a server can accept session identifiers by multiple means. This is usually the case when a back-end is used for websites and mobile applications. A session identifier is a token stored on the client-side.
Which is the best approach to session management?
Common approaches used include utilizing Sticky sessions or using a Distributed Cache for your session management. These approaches are described below. Sticky sessions, also known as session affinity, allow you to route a site user to the particular web server that is managing that individual user’s session.
Can a session be abstracted from a web server?
If not mitigated properly, this can hinder the scalability of your applications. In order to address scalability and to provide a shared data storage for sessions that can be accessible from any individual web server, you can abstract the HTTP sessions from the web servers themselves.
