QlikView WebTicket: Changed behavior in URL handling in 11.20 SR14 and later

Due to some bug fixes in the web ticket feature, the handling or URL has changed in 11.20 SR14. Web Ticket solutions that use the old URL format will need to be updated to work properly.

This is due to the fix of the following bugs:
QVII-392 - AJAX client using multiple select= parameters doesn't work with web ticketing
QVII-1118 / QV-6388 - AJAX client using multiple select= parameters doesn't honor second parameter with web ticketing

URL in the following format will not work in 11.20 SR 14 and later:

http://qlikserver1.domain.local/QvAJAXZfc/Authenticate.aspx?type=html&try=http%3A%2F%2Fqlikserver1.domain.local%2FQvAJAXZfc%2FAccessPoint.aspx%3Fopen%3D%26id%3DQVS%2540qlikserver1%257Cmovies%2520database.qvw%26client%3DPlugin&webticket=ticketnumber
(Notice the double-encoding of special characters in the string: QVS%2540qlikserver1%257Cmovies%2520database.qvw

The URL now needs to be in the following formats:
http://qlikserver1.domain.local/QvAJAXZfc/Authenticate.aspx?type=html&try= http%3A%2F%2Fqlikserver1.domain.local%2FQvAJAXZfc%2FAccessPoint.aspx%3Fopen%3D%26id%3DQVS%40qlikserver1%7Cmovies%20database.qvw%26client%3DPlugin&webticket=ticketnumber
(Simple encoding of the whole string)

OR

http://qlikserver1.domain.local/QvAJAXZfc/Authenticate.aspx?type=html&try= http://qlikserver1.domain.local/QvAJAXZfc/AccessPoint.aspx?open=%26id=QVS@qlikserver1|movies%20database.qvw%26client=Plugin&webticket=ticketnumber
(encoding of & in the try parameter string only)
