saml redirect after reauthentication not to original position

Hello,

 

i have setup a working ASM Profil. BigIP is SP and a external IdP. All works well but if a clinet work on the website (like: /folder1/wathever.aspx) and get a reauthentiction he get not back to the orignal position "/folder1/wathever.aspx", he get to "/" . But i can't found a configuration otion to solve this.

 

Can anyone help me?
