Question 1

CORS: Concept, Solution and Risks in REST API with API Key

Accepted Answer

Origin of CORS Error

CORS, an acronym for Cross-Origin Resource Sharing, is a mechanism implemented in web browsers to allow the resources of a web page to be requested from a domain other than the one that served the first page. This mechanism is designed to protect the user from malicious attacks that could compromise their data through cross-site requests.

The CORS error arises when a web application tries to make a request to an API that is hosted on a different domain than the application. For example, if your application on https://miapp.com tries to access an API on https://api.externo.com, the browser will block the request due to its same origin policy, unless the external API has Properly configured CORS headers to allow requests from your domain.

CORS Error Example

Without proper CORS configuration, an AJAX request from https://miapp.com to https://api.externo.com would fail:

fetch("https://api.externo.com/datos")
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error('Error al realizar la petición:', error));

The browser will display an error similar to:

Access to fetch at 'https://api.externo.com/datos' from origin 'https://miapp.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Solution: Enable Origin Domain

To resolve the CORS error, the API server must include the Access-Control-Allow-Origin head

Question 3

What is the difference between CTR and CTOR?

Accepted Answer

Two of the key metrics that are commonly used to measure the performance of an email marketing campaign are click through rate (CTR) and click through rate (CTOR). While they may look similar, each offers valuable insight into subscriber behavior and can help you optimize your marketing strategies.

Difference between CTR and CTOR.

CTR, or click-through rate, is a metric that tells you the proportion of recipients who clicked on one or more links within your email, out of the total number of emails actually delivered. The formula for calculating CTR is quite simple: divide the number of clicks by the number of emails delivered and multiply by 100 to get a percentage.

The CTR is an important indicator to evaluate the level of interaction and commitment of your subscribers with your emails. A high click-through rate generally indicates that your posts are relevant and engaging to your audience. On the other hand, a low CTR may indicate that your emails are not capturing the attention of your subscribers or that the content is not interesting to them.

CTOR, or click-through rate on unique views. This metric goes a step further and focuses on the number of clicks made by recipients relative to unique views of the email. In other words, CTOR shows you what percentage of the people who actually viewed your email interacted with it by clicking on the links.

To calculate CTOR, divide the number of clicks by unique views and then multiply by 100 to get a percentage. Un
