Scenario: A Citrix Engineer configures Citrix Web App Firewall to protect an application. Users report that they are NOT able to log on. The engineer enables a Start URL relaxation for the path //login.aspx.
What is the effect of the Start URL relaxation on the application?
A Start URL relaxation in Citrix Web App Firewall is used to allow access to specific paths that are otherwise restricted. By configuring a Start URL relaxation for the path /login.aspx, the Citrix Engineer permits access to this login page, hence resolving the issue that users were facing when they could not log in. Therefore, enabling a Start URL relaxation unblocks access to the specified path, allowing legitimate traffic to pass through.
This is the correct answer. The Start URL check is designed to block connections if the URL does not meet the specified criteria, which includes matching an entry in the Start URL list. By adding a relaxation for //login.aspx, the Citrix Engineer is allowing this URL to be accessed, which would enable users to reach the login page that they were previously unable to access due to the firewall's restrictions.
