Troubleshooting Tip: Logout page enters redirect loop due to content routing URL mismatch

Description

This article explains a scenario where users are unable to log out of a web application published through FortiWeb and encounter a browser error indicating excessive redirects (HTTP 307).

Scope

FortiWeb.

Solution

Users may experience a redirect loop when accessing or logging out of an application published through FortiWeb.

The issue may occur when the configured Content Routing URL does not match all application URL variations.

In the scenario investigated in this article, the Content Routing policy was configured to match the following:

/fss/

However, requests for URLs containing the following did not match as expected:

/fss

This caused the backend application to issue repeated HTTP redirects and resulted in an infinite redirect loop.

To resolve the issue, modify the Content Routing match prefix to this:

/fss

This allows both URL formats to be handled correctly:

/fss
/fss/

After updating the Content Routing policy, the logout process completes successfully and the redirect loop is resolved.
