“ERR_TOO_MANY_REDIRECTS” in IIS

The “ERR_TOO_MANY_REDIRECTS” issue in IIS (Internet Information Services) appears when a website gets stuck in a loop of redirections, forcing the browser to see several redirects without ever arriving at the desired location. This error often denotes an incorrect configuration of the server or website.

Causes & Solution of “ERR_TOO_MANY_REDIRECTS” in IIS

1: Misconfigured URL Rewrite Rules

It is likely that the configuration of URL rewriting rules in IIS that we are using is incorrect, resulting in a redirect loop.

Solution: We need to check the URL rewrite rules in the web.config file or the IIS URL Rewrite module and ensure they are correctly defined. Review any conditions or patterns that could result in an infinite loop.

2. Incorrect HTTP to HTTPS Redirects

If we’ve set up HTTP to HTTPS redirects, a bad configuration could result in a redirect loop.

Solution: We need to make sure the redirect configuration are proper, and there are no conflicts or circular redirects. Double-check the rules in the web.config file or any other configuration files responsible for the redirects.

3. Improper SSL Certificate Configuration

An erroneous SSL certificate configuration can result in redirection problems if the website employs SSL/TLS encryption (HTTPS).

Solution: We must make sure the installation of the SSL certificate is proper and matches the domain of the website. Check the IIS server setup for any certificate-related issues or warnings.

4. Conflicting Server Settings

Competing server configurations, such as multiple virtual hosts or competing rewrite rules, might occasionally result in a redirect loop.

Solution: We need to check the server configuration to make sure there are no incompatible settings, including virtual host settings, server-level redirection, and any other pertinent settings.

5. Caching or Proxy Issues

Redirect loops can occur when caching or proxy servers prevent redirects from working properly.

Solution: We must review the configurations of any cache or proxy servers we may be using in front of our IIS server to make sure they aren’t causing any problems or unintentionally changing the redirect behavior.
