What is a redirect loop?

A redirect loop is a website problem where a webpage keeps redirecting users from one URL to another repeatedly without reaching the final page. This creates an endless cycle of redirects, and the browser is unable to open the website correctly. When this happens, users may see messages such as “Too Many Redirects” or “This page isn’t working.” Redirect loops are common in websites when redirect settings are not configured properly.
For example, Page A redirects to Page B, and Page B again redirects back to Page A. Because both pages continue sending visitors to each other, the browser gets stuck in a loop. This issue can happen due to incorrect HTTPS settings, plugin conflicts, wrong .htaccess rules, or mistakes in website configuration.
Redirect loops can negatively affect user experience because visitors cannot access the website content. They may also harm search engine optimization (SEO) since search engines may face difficulty crawling the pages. Website owners should regularly test redirects and check server settings to avoid such problems. Fixing redirect loops improves website performance, user satisfaction, and search engine visibility. Therefore, the correct answer is A. Endless redirect cycle.
