illegal redirection

I have created a lab setup with dvwa application server. And have placed the server behind F5. Before placing the server behind F5, I had tried XSS stored and had tried a url redirection using

.Now if i go XSS store, it redirects. So the DB is already corrupted. Now if i place the server behind F5, can i avoid this behaviour using the redirection protection , without doing any change in DB . I just want to block the redirection, so that user doesn't see the redirected page.Can i do it with F5 ?
