Current HttpServletRequest

The current `HttpServletRequest` object provides information and functionality for handling HTTP requests in a Java Servlet environment. It represents the request made by a client to the server and contains methods to access various parts of the request, such as headers, parameters, cookies, and the request body.

You can obtain the current `HttpServletRequest` object in a Servlet using the `doGet()`, `doPost()`, or other similar methods by passing it as a parameter:

protected void doGet(HttpServletRequest request, HttpServletResponse response) {
    // Access request information using the HttpServletRequest object
    // ...
}

Once you have the `HttpServletRequest` object, you can use its methods to retrieve information about the request, such as:

- `getMethod()`: Returns the HTTP method of the request (e.g., GET, POST).
- `getHeader(String name)`: Returns the value of the specified request header.
- `getParameter(String name)`: Returns the value of the specified request parameter.
- `getCookies()`: Returns an array of `Cookie` objects representing the cookies included in the request.
- `getInputStream()`: Returns an input stream for reading the request body.

These are just a few examples of the methods available in the `HttpServletRequest` class. You can refer to the Java Servlet API documentation for more details on how to work with this object.
