Servlet Descriptors - iAS Params Tab

iAS Params (Servlets)

You use the iAS Params tab to validate servlet parameters (for example fields on a HTML form) and is used when the Validation Required box is checked on the iAS tab. A typical request-reponse cycle goes through several phases, the first of which is the checking required to ensure that the user has supplied all the correct input, and that the user is properly authenticated for the requested access. Note that this validation is not for complex validation such as credit checks.

The validation scheme needs a URL to call when errors have been accumulated. This is done on the Error Handler fields on the iAS tab.
