Login redirect rules

I'd like to modify my user login page created with databridge security assist.

My user update page allows the admin user to enable or disable access to each page for each standard user account.

If when a standard user attempts to access a protected page (without logging in) they get redirected to the login page

I want to modify the redirect posted url variable to include go=1. The value will be set according to the page the user was redirected from, eg go=2, go=3 etc.
i guess so it looks something like this:-

../uacLOGIN.php?go=1&accesscheck=%2Fdevices%2F

I want to use that value in a show region rule to display custom alert text on the login page each time a rule is met in this scenario.

It seems straightforward enough, I just need to append the new variable as described to the redirect url. However, this process appears to be handled by WA proprietary code.

How can i achieve this?

It seems like you can just update the failed redirect on the restrict access to page server behavior and add the url parameter. (if I'm understanding your question correctly)

Thanks, that worked.
