How are HTTP session cookies handled in servlets?
- Cookies are handled automatically by servlet containers.
- Cookies are managed using the Cookie class.
- Cookies are not supported in servlets.
- Cookies must be handled manually in the doGet() method.
In servlets, HTTP session cookies are typically managed using the Cookie class, allowing developers to handle cookie creation, retrieval, and manipulation programmatically.
The __________ method of the ServletContext interface is used to retrieve context parameters.
- contextParam()
- getContextParameter()
- getInitParameter()
- retrieveParameter()
The getInitParameter() method of the ServletContext interface is used to retrieve context parameters associated with the servlet's context.
Session tracking using ________ involves storing a small piece of information on the client's browser.
- Cookies
- Hidden Fields
- Session ID
- URL Rewriting
Session tracking using Cookies involves storing a small piece of information on the client's browser.
To access the MIME type of a file, use the __________ method of ServletContext.
- analyzeMimeType()
- fetchMimeType()
- getMimeType()
- retrieveMimeType()
To access the MIME type of a file, use the getMimeType() method of ServletContext.
In a scenario where form data includes special characters like & and %, which approach ensures accurate data retrieval?
- Apply Base64 encoding to the form data
- HTML-escape the special characters
- URLEncode the form data before processing
- Use the raw form data directly
URLEncoding the form data before processing ensures accurate data retrieval, especially when dealing with special characters like & and %. This encoding prevents issues with parsing and processing the data correctly.
In a scenario where a cookie is used for authentication, what measures should be taken to enhance security?
- All of the above
- Encrypt the cookie data
- Store minimal information in the cookie
- Use HTTPS
To enhance security in cookie-based authentication, it's crucial to use HTTPS, store minimal information, and encrypt the cookie data.
ServletConfig is used to pass __________ to a specific servlet during initialization.
- configuration
- context
- parameters
- resources
ServletConfig is used to pass initialization parameters to a specific servlet during initialization.
The _________ method of HttpServletRequest is used to parse query parameters from the request URL.
- getParameter()
- getQueryParameters()
- parseQueryParameters()
- retrieveQuery()
The getParameter() method of HttpServletRequest is used to parse query parameters from the request URL.
How is ServletConfig initialized?
- Automatically by the container
- Using a configuration file
- Using constructor
- Using init() method
The ServletConfig is automatically initialized by the container. It provides configuration information to the servlet and can be obtained using the getServletConfig() method.
What is the difference between context parameters and initialization parameters in servlets?
- Context parameters are set at the application level, while initialization parameters are specific to a servlet.
- Context parameters are used for database connectivity, while initialization parameters are used for servlet configuration.
- Initialization parameters are set at the application level, while context parameters are specific to a servlet.
- Initialization parameters are used for database connectivity, while context parameters are used for servlet configuration.
Context parameters are set at the application level and are accessible to all servlets, while initialization parameters are specific to each servlet and are defined in the servlet's deployment descriptor (web.xml).
