What's going on with 301 when building PHP in IIS?

IIS is web server software for Microsoft Windows servers, while PHP is a popular server-side scripting language. IIS paired with PHP is a very common website development environment, but during the construction process, you may encounter 301 redirect errors. This article will explain what 301 is, why it occurs when setting up IIS and PHP, and how to solve 301 redirect errors.

What is a 301 redirect error?

301 redirect means that the website's server tells the browser that the web page has moved to a new address. This usually happens when you change your website's URL structure, restructure your site, or place the same content on a different domain name.

A common reason is that the links in the website are not changed correctly, causing the browser to be unable to find them. When the browser cannot find the link, the server issues a 301 redirect error.

Why do 301 redirect errors occur during IIS and PHP setup?

When you build a PHP website on IIS, you must ensure that IIS correctly configures the PHP processor. If you do not configure the PHP processor correctly, IIS will decide which processor to send the page to based on the file type requested. If IIS decides to send a PHP page to an ASP.NET processor, or an ASP.NET page to a PHP processor, a 301 redirect error will occur.

How to solve 301 redirect error?

The easiest way to resolve 301 redirect errors is to check your IIS and PHP configuration. Here are some common solutions:

1. Make sure you have the PHP handler installed correctly.
2. Make sure you have correctly configured the PHP processor in IIS.
3. Check your website's base directory and make sure your file extensions match your IIS configuration.
4. Make sure your website’s cache is cleared.
5. Check whether the website has been refactored or renamed.

Finally, if you have tried all the solutions and still cannot resolve the 301 redirect error, then the best solution is to seek professional help. You can contact your IIS and PHP website developer or hosting provider for additional support and assistance.

Summary

301 redirection error is a very common problem, especially in IIS and PHP website construction. Properly configuring IIS and PHP processors as well as checking file extensions and website cache may resolve 301 redirect errors. If you are not successful in resolving the error, be sure to seek professional help.
