# How can you share data between Servlets?

Sharing [data](https://www.mindstick.com/articles/13050/salesforce-aiming-to-dominate-predictive-analytics-with-data-science) between servlets is like passing notes between friends. In the world of servlets, there are several ways to achieve this:

## Servlet Collaboration - RequestDispatcher:

- One servlet can forward a request to another servlet using **RequestDispatcher**. It's like passing the note to a friend and asking them to handle part of the task.

## Using ServletContext:

- The **ServletContext** is like a common bulletin board for all servlets. One servlet can set an attribute, and another servlet can retrieve it.

## URL Rewriting:

- Data can be passed between servlets through URL parameters. It's like including a note in the URL for the other servlet to read.

## Session Objects:

- Data can be stored in a session, and any servlet within the same session can access it. It's like passing a note that stays with a friend throughout the conversation.

These are different ways to share data between servlets, each with its own use case. Choose the method that fits the requirements of your application.
