Bug: Short URL with slash "/" character

[wutsqo]

Current behavior:
Users can enter a short URL that contains a slash character. It counts as valid, but when the user enters the short URL, it will redirect to a 404 page.

Proposed Solution:
Add new validation rules on the front end and the server-side to prevent such thing happens.

can we add link validator? if the url is not the valid link it will show an error

I think that will be good idea, client-side validator (such as pop-up message) will be enough
