What is a request response cycle?
The request/response cycle traces how a user’s request flows through the app. Understanding the request/response cycle is helpful to figure out which files to edit when developing an app (and where to look when things aren’t working).
What is request life cycle?
The request life cycle begins at the Start block and completes at the End block. When the request is created, only status/es connected to the Start are displayed to the user. Similarly, the request flow is considered to be closed only when the request reaches a status connected to the End block.
Who initiates the process of request response cycle?
The request/response cycle. The request/response cycle involves many components, especially if the request is to a controller-endpoint which interacts with the database. The request handling process starts with the app’s sequence; it is the gatekeeper of all requests to the app.
What is HTTP request and response life cycle?
Every Http request first contacts a DNS server which resolves the request URL domain to a IP address. After fetching the Webserver IP address request is forwarded to it(via PUT request). A webserver like apache handles this request and forwards this to application which has to handle this.
What is the difference between request and response?

How to understand the request / response cycle in loopback?
To understand the LoopBack 4 request/response cycle, let’s start by enumerating the APIs that create the endpoints on the server. We will then follow the path taken by a request, to see how it makes its way through the various parts of the framework to return a result.
How does the server respond to a request?
Once the client’s request has reached the server, the server will search for and return the information the client is requesting. Often times, this means querying a database, loading the information into an html page, and returning the HTML text to the user in the body of the HTTP response.
