If a request is received that does not match any of the defined URL patterns, then the definition for * is used to determine to what servlet the request is dispatched.

If you access something after /prweb and the servlet is not found, you are redirected to the default servlet, where * is configured as the URL pattern.

If the * URL pattern is not provided, then system becomes inaccessible. * is the minimum servlet requirement for a servlet to be accessible. Without *, the servlet produces a 403 error. The Servlet Management landing page provides a validation to ensure that at least one servlet is in the Enabled state with * as the URL pattern.

1. Access the servlet from which you want to move the * URL pattern:
   1. In the header of Dev Studio, click ConfigureSystemSettingsServlet & Filter Management Servlet.
   2. Identify the servlet from which you want to remove the * URL pattern, click the More icon on the right side of the window, and then select Configure.
   3. Under URL patterns, click the delete icon beside the * URL pattern.
   4. Click Update.
2. Add the * URL pattern to the servlet that you want to update:
   1. Identify the servlet to which you want to add the * URL pattern, click the More icon on the right side of the window, and then select Configure.
   2. Under URL patterns, click Add.
   3. Enter the * URL pattern.
   4. Click Update.
   5. Restart your entire environment from My Pega Cloud.
