The HTTP RESPONSE message
Consider the figure below, where the server is sending a HTTP RESPONSE message back the client.
Suppose the server-to-client HTTP RESPONSE message is the following:
HTTP/1.1 404 Not Found
Date: Sat, 23 Nov 2024 11:54:41 +0000
Server: Apache/2.2.3 (CentOS)
Content-Length: 4982
Keep-Alive: timeout=50, max=83
Connection: Keep-alive
Content-type: text/html
Question List
1. Is the response message using HTTP 1.0 or HTTP 1.1?
2. Was the server able to send the document successfully? Yes or No
3. How big is the document in bytes?
4. Is the connection persistent or nonpersistent?
5. What is the type of file being sent by the server in response?
6. What is the name of the server and its version? Write your answer as server/x.y.z
7. Will the ETag change if the resource content at this particular resource location changes? Yes or No
Solution
1. The response is using HTTP/1.1
2. Since the response code is 404 Not Found, the document was NOT received successfully.
3. The document is 4982 bytes.
4. The connection is persistent.
5. The file type the server is sending is text/html.
6. The name and version of the server is Apache/2.2.3
7. Yes. The Etag is a string that uniquely identifies a resource. If a resource is updated, the Etag will change.
