Answer the following question?
Transcribed Image Text:**Explaining Inter-Server Data Requests in Web Architecture**
**Question:**
Using only your own words (do NOT quote in any way from any source), briefly explain what happens when a web server receives a request that requires it to obtain data from another server in order to prepare the response.
Hint: The focus of this question is the client-server paradigm.
**Answer:**
When a web server receives a request that necessitates additional data from another server, it acts as an intermediary in the process. Here is a step-by-step explanation of what generally occurs:
1. **Request Reception:** The initial server receives a request from a client (such as a web browser).
2. **Data Requirement Identification:** The server identifies that it requires additional data from another server (often a database server or a microservice).
3. **Inter-Server Communication:** The initial server sends a request to the second server asking for the required data.
4. **Data Retrieval:** The second server processes this request and sends the necessary data back to the initial server.
5. **Response Preparation:** The initial server uses the data received from the second server to prepare a complete response for the original client request.
6. **Response Transmission:** Finally, the initial server sends the prepared response back to the client.
This process highlights the client-server paradigm where multiple servers may interact with each other to fulfill client requests efficiently.
