I would need more data here. It is really hard to comprehend why would your url reply with the backslash (\) inside the redirection link

[programmerdr]

get data header with live http header when use \ on url get response sql syntax error and when forward url to redirect

some times use * or ' url redirect but and easily injected but my target when use \ get sql syntax error on page
sqlmap can not inject this i have many target with use this character on url get error syntax and no one can not help me for this
