Complete the Custom tab to specify how credential challenges and timeouts are managed.
| Field | Description | 
| Secure Authentication | |
| Use SSL | Select to require that users be authenticated through a Secure Sockets Layer secure port: that is, they must use an HTTPS URL for authentication. If selected, verify that the application server hosting PRPC uses HTTPS and that a URL is configured with the appropriate security constraints. | 
| Initial challenge stream | 
                             See the standard HTML rule Web-Login-SecuredBasic for an example. By default, this rule runs when all of the following are true: 
 | 
| Challenge Options | |
| Use Basic Authentication for sign on | Select to instruct PRPC to use the Basic Authentication browser pop-up window to gather user credentials. | 
| Credential challenge stream | 
                             | 
| Timeout Options | |
| Use PegaRULES Timeout | Select to cause PRPC to use the authentication timeout value specified in the user access groups to determine how long a user's session can remain inactive before users are prompted to identify themselves again. Leave this option cleared if timeout is managed by the application server or other facility external to PRPC. | 
| Use Basic Authentication for timeout | Select to instruct PRPC to use the Basic Authentication browser pop-up window to gather credentials when a user's session times out. | 
| Timeout Challenge Stream | Identify the second key part of an HTML rule (where the Applies To key part is @baseclass) that presents a form for gathering user credentials when the user's session times out. | 
| Redirect URL | Optional. Enter a URL. PRPC redirects the user to the URL specified in this field when the user's session times out. This field is not available when the Use PegaRULES Timeout option is selected. |
