APM - Redirect without closing the SSO session

I have an access policy that check if a user requested a SAML resource of Box.com and if the user is in an AD group. If the user is not a in the AD group the access policy it goes to a redirect terminal. The biggest issue is I have to have the terminal close the session or I get an error (connection reset) redirecting btw I'm redirecting to the same URL as the APM.

Is the error due to me using the same virtual server to do logins and show error messages?

My login page is https://bxapp.corp.com/My.policy and the redirect page is https://bxapp.corp.com/samlerror/box

I have an iRule that checks the URL for the string samlerror.

when HTTP_REQUEST {
    if { [HTTP::uri] contains "samlerror" } {
        log local0. "Saml Error URI-> [HTTP::uri]"
        log local0. "Saml Error PATH-> [HTTP::path]"

        set errorBody "Error connecting using SAML - Single Sign On"
                switch -glob [string tolower [HTTP::path]] {
            "/samlerror/box/*"  {
                log local0. "BOX >> User has no access to box via AD group"
                set errorBody "Your account doesn't have access to Box.com Please contact the IT Service Desk"
            }
            default {
                log local0. "DEFAULT >> Saml Error [HTTP::uri]"
            }
        }

        set htmlBody "SSO Error"
    removed html code
            append htmlBody ""
        append htmlBody $errorBody
        HTTP::respond 200 content $htmlBody
    }
}
