How to remove multiple slashes

Developer help

Hi!

The problem is that my regular expression doesn’t working for all cases.

{
    "from": "^(.*?)/+/(.*)$",
    "to": "$1/$2",
    "permanent": true
}

Not working for http://example.com//tag/cat/something/.
But working, if added 1 or more slashe(s) to URL => http://example.com/tag/cat/something/.
