Is the following statement true or false. URL rewriting may be used when a browser is disabled. In URL encoding the session id is included as part of the URL

technology web technology

  1. True

  2. False

Show answer
Correct Option: A

AI Explanation

To answer this question, we need to understand the concepts of URL rewriting and URL encoding.

URL rewriting is a technique used to modify the URL of a web page dynamically. It is commonly used to create user-friendly URLs or to maintain session information. When a browser is disabled, URL rewriting can still be used to modify the URL.

URL encoding, on the other hand, is a technique used to convert special characters into a format that can be transmitted over the internet. It is commonly used to include parameters or data in the URL. The session id can be included in the URL through URL encoding.

Now let's analyze the given statement and each option:

Option A) True - This option is correct. URL rewriting can be used even when a browser is disabled. In this case, the server can still modify the URL to include session information.

Option B) False - This option is incorrect. URL rewriting can be used when a browser is disabled.

The correct answer is A) True. URL rewriting may be used when a browser is disabled, and the session id can be included as part of the URL through URL encoding.

Explanation:

To answer this question, the user needs to have knowledge about HTTP response status codes.

Now, let's go through each option and explain whether it is correct or incorrect:

A. A status of 200 to 299 signifies that the request was successful. This statement is correct. HTTP status codes in the 200 range indicate that the client's request was successful and the server responded with the requested resource.

B. A status of 300 to 399 are informational messages. This statement is incorrect. HTTP status codes in the 300 range indicate that the server is redirecting the client's request to a different location.

C. A status of 400 to 499 indicates an error in the server. This statement is incorrect. HTTP status codes in the 400 range indicate that the client's request was incorrect or invalid, and the server could not understand it.

D. A status of 500 to 599 indicates an error in the client. This statement is incorrect. HTTP status codes in the 500 range indicate that the server encountered an error while trying to fulfill the client's request.

Therefore, the correct answer is:

Option B) setContent - This option is incorrect because there is no method named "setContent" in the HttpServletResponse class for setting the content type.

Option C) setContentType - This option is correct because the HttpServletResponse class does have a method named "setContentType" that can be used to set the content type.

The correct answer is option C) setContentType. This option is correct because the setContentType method is defined in the HttpServletResponse class and is used to set the content type.

Explanation:

To understand the type of HTTP request generated, the user needs to know the following:

Based on this information, the correct answer is:

The Answer is: A (GET method)

The GET method is used to request a representation of the specified resource.

Option B (/classes) is also incorrect because there is no such directory in a typical war file.

Option D (/root/classes) is incorrect because there is no root directory in a war file.
