To enable and configure the HTTP Redirect module of IIS to implement 301 or 302 redirection, you need to complete the following steps in turn: First, enable the HTTP Redirect module in the Windows function; then select the site or page in the IIS manager, double-click "HTTP Redirect" to set the target URL and select the redirect type (permanent or temporary); finally pay attention to avoid conflicts with other modules, clear browser cache, ensure correct permissions, and achieve more granular control through the web.config file.

Setting up permanent or temporary URL redirects is very common when you are maintaining, migrating, or optimizing your website. If you are using IIS (Internet Information Services), you can implement it through the HTTP Redirect module, and the operation is not complicated.

How to enable the IIS HTTP Redirect module

IIS may not have this module installed by default, so the first step is to confirm that it is enabled.
If it is a Windows Server system, you can add roles and functions in "Server Manager" and check "HTTP Redirection" in the function options of IIS.
For local development environments such as IIS on Windows 10 or 11, go to Control Panel > Programs > Enable or Turn off Windows Features, and make sure that HTTP Redirect in IIS > WWW Services > Application Development Features is selected.

If you are not sure if it is enabled, you can also open IIS Manager, select the site or application, and see if there is an "HTTP Redirect" icon in the "IIS" section of the homepage.

Configure permanent (301) or temporary (302) redirects

Once the module is ready, you can configure the redirection next. The operation steps are as follows:

• Open IIS Manager and select the site or page you want to set up redirects
• Double-click the "HTTP Redirect" icon
• Check "Redirect request to this destination"
• Fill in the target URL (can be a relative path or a full address)
• Select "Redirect only if the request is HTTP" (optional)
• Set status code: permanently select "Permanent (301)" and temporary select "Temporary (302)"
• Click "Apps" in the upper right corner

Here are a few details to pay attention to:

• If you only want to redirect a subpage instead of the entire site, you can enter the corresponding folder or page node in the connection tree on the left and then set it.
• The target URL is best to bring a protocol header (such as http:// or http://www.miracleart.cn/link/645d8981d8d3547c17119dda7d6c057a .
• If "Redirect all requests to the end destination" is enabled, even if there are multiple redirect rules in the middle, they will jump directly to the last destination.

Frequently Asked Questions and Precautions

Sometimes, after setting up, it is found that it does not take effect, or the jump logic is incorrect, which may be the following reasons:

• Conflict with other modules : For example, the URL Rewrite module may also be dealing with redirects, and it is necessary to check whether rules are overwritten by each other.
• Cache affects test results : The browser cache may cause you to think that the modification is not effective. It is recommended to use invisible mode or clear the cache before testing.
• Permissions Issue : In some cases, especially in shared hosting environments, there may be no permission to change the web.config file or use the module.
• web.config is overwritten by manual editing : modifying through the IIS management interface will automatically update web.config, but if someone manually corrects the configuration file, it may lead to conflicts.

If you want to control more carefully, you can also write configurations directly in web.config, for example:

 <configuration>
  <system.webServer>
    <httpRedirect enabled="true" destination="https://newsite.com" httpResponseStatus="Permanent" />
  </system.webServer>
</configuration>

This method is suitable for automated deployment or batch configuration of multiple sites.

Basically these are the operations. Although it seems a bit too many, it is actually very fast to set it up later as long as you are familiar with the process once. The key is to understand the role of each option and avoid mismatch causing access exceptions.
