no, you cant have 2 redirects, but this can be done by setting a column in the users table to indicate whether they have performed the inert or not.
in the users table create a column named regComplete set the default value to 0
On the insert data page, update the regComplete column to 1 when the data is inserted.
On the login page, edit the Security Assist Authenticate user behavior, go to the Session Variables section and click the plus button, select the regComplete column to have it stored in a session on login, make note of the name that is used. also make note of the UserID session variable name.
For the sake of example, I am going to use "SecurityAssist_UserID" and "regComplete" going forward, you will need to make sure to use the correct session names when following the steps I outline
now you will need to create a new access rule, go to WebAssist -> Security Assist -> Manage Site Access -> Access Rules Manager
Set the name to Completed registration.
Create a condition, select the Restrict radio button. For Value, click the lightning bolt icon and select the SecurityAssist_UserID session variable binding. Set the Criteria to "=" and leave the compare to field blank.
Create another condition, select the Allow radio button. For Value, click the lightning bolt icon and select the regComplete session variable binding. Set the Criteria to "=" and set the Compare to field to 1
Now on the Update Data page, add the page access restriction to allow access only if the Completed registration rule passes.
