The answer is that a 302 redirect to a login page in Burp Repeater most likely means the session token has expired and the user must re-authenticate. This occurs because the web application uses a server-side session management mechanism; when the session times out, the server invalidates the token and issues a 302 redirect to enforce re-authentication before granting access to protected resources. On the Certified Ethical Hacker CEH exam, this scenario tests your understanding of session handling and HTTP status codes in web application attacks—a common trap is mistaking the redirect for a successful logout or a CSRF token mismatch. Remember, a 302 to login is the application’s way of saying “your key no longer works,” not a sign of a blocked request. Memory tip: “302 to login = session kicked in.”
CEH Web Application and Injection Attacks Practice Question
This CEH practice question tests your understanding of web application and injection attacks. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
During a web application penetration test, a tester uses Burp Suite's Repeater tool to manually manipulate a request and observe the response. After sending the same request multiple times, the application returns a 302 redirect pointing to a login page. What is the MOST likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The session token has expired and the user must re-authenticate
A 302 redirect to a login page typically indicates that the session has expired or the tester's session is no longer valid. The application is redirecting to enforce authentication.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
The server is rate-limiting the requests
Why it's wrong here
Rate-limiting would likely return a 429 Too Many Requests error, not a 302 redirect to login.
✗
A cross-site request forgery (CSRF) token mismatch occurred
Why it's wrong here
CSRF token mismatch would typically result in a 400 Bad Request or an error page, not a 302 redirect to login.
✓
The session token has expired and the user must re-authenticate
Why this is correct
After repeated requests without refreshing the session, the token may expire, causing a redirect to the login page.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
The server detected the use of a proxy and blocked the request
Why it's wrong here
Blocking due to proxy detection would likely return a 403 Forbidden or a block page, not a redirect.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CEH exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
