I am working on one site where I need to show 404 pages when someone adds double slash in URL.



I have written logic to check REQUEST_URI and if there is double slash then I am showing 404 pages...



But when I add double slash in URL it shows single slash in REQUEST_URI but in URL, it is double slash...



here I attached a screenshot for the same issue.




For Example: if i enter www.example.com//check -> then its is coming
as /check in REQUEST_URI but i want it should come as //check



Site is hosted in AWS cloud load balancer (ELB). in local setting its
working proeper but in production its creating issue.




Can someone help me how can I prevent this?

If the problem is that Google has indexed the double slash version as well as the regular path, then it's better to use a redirect to send google to the correct path.



As you tagged this question with nginx, the easiest solution is to use a selective rewrite, such as:



location / 
if ($request_uri ~ ^//)
rewrite ^/.* $uri permanent;

[...]



This works because $request_uri is the original URI, while $uri is the normalized one. The rewrite statement replaces the complete URI with the normalized one, so that Google knows that the double slash version is to be replaced by the normalized one.
