You can first enable FRT to learn from where the 302 response comes from https://learn.microsoft.com/en-us/previous-versions/troubleshoot/iis/troubleshoot-failed-requests-using-tracing-in-iis-7

Hi @Arutprakasam,

HTTP 302 Found is a redirect response, usually means "Moved Temporarily". Use browser developer tools to inspect network requests, it can provide additional information about the redirect. Look for the "Location" header, which indicates the URL to which the request is redirected. The source is either in the web server settings or in the application itself, so no one knows but you.

In IIS Manager, check your site level and server level respectively to see if the following modules are configured:

"URL Rewrite" module

"HTTP Redirect" module

On the IIS server, viewing the log files may provide more information about the 302 status code. Check the IIS log file to see which resource was redirected and see where the "Location" header was targeted.

If the IIS logs do not provide enough information, check your API code to see if any explicit 302 redirects are set in the code.

Regardless, even in valid scenarios you may see HTTP 302, which is not an error in itself. If you need help diagnosing a problem, you'll need to post detailed IIS configuration information and network request logs.

Hi @Yurong Dai-MSFT ,

Absolutely thank you for the detailed answer.

you have mentioned headers in your answer. Shall I know what is headers?

Also I missed to share one detail with you. we are hosting the application in windows server 2019 iis 10. Previously we are maintained everything in windows server 2012 iis 8. In old server same code is working properly but in new server it's throwing the error 302.

Also Please share the document for updating the HTTP redirect and URL Rewrite installation details.

Hi @Arutprakasam,
One specific response header relevant to your question is the Location header. It is used to provide the URL to which the client should be redirected to a specific resource. In the context of HTTP status code 302 Found, the Location header is typically used to indicate a temporary redirect URL.

Example 302 response with header Location:

HTTP/1.1 302 Found

Location: https://www.example.com/new-location

If your API returns a 302 status, inspecting the Location header in the response can provide insight into where the temporary redirect is pointing. This header is critical to understanding redirects and can be helpful in debugging and resolving issues related to unexpected redirects.

In addition, you only need to check whether your HTTP redirection module and URL rewriting module have redirection configured, no need to reinstall them.
