Double slash at the end of base path of url

[#1]

How to handle double slash at the end of base path of url?

Lets say I have proxy setup having base path as below:

https://myorg.apigee.net/subpath

which handles all the conditional flow hitting above url.

Then I have proxy with base path as below to handle invalid resource url:

https://myorg.apigee.net/

But, if I hit below url,

https://myorg.apigee.net//

It gives:

{"fault": {"faultstring": "Invalid path GET // HTTP/1.1","detail": {"errorcode": "protocol.http.InvalidPath"}}}

How to handle this invalid double slash and return customize error message.

Thanks,
