F5 BIG-IP LTM Specialist: Maintain and Troubleshoot — Question 100

The end users of a web application need to verify that their browsers received the complete message-body from the web server.
Which HTTP header will accomplish this?

Answer options

• A. Range
• B. Expect
• C. Accept-Ranges
• D. Content-Length

Correct answer: D

Explanation

The Content-Length header indicates the size of the message body in bytes, allowing browsers to verify if they received the complete content. The Range header is used for partial content requests, Expect is for indicating expectations from the server, and Accept-Ranges specifies if the server accepts range requests, none of which confirm the total message body size.
