javalearner, if http://www.example.com/v1 is a fixed part of your match, it looks to me like you could go with something as simple as

if (/http:\/\/example\.com\/v1\/[^\/]+\/[\w=?]+/.test(subject)) { // Successful match } else { // Match attempt failed }

However, if that part is not fixed, you could go with something like

if (/(?:https?|ftp):\/\/[a-z\d-]+\.[a-z]{2,6}\/[^\/]+\/[^\/]+\/[\w=?]+/.test(subject)) { // Successful match } else { // Match attempt failed }

Note that the {2,6} allows for matching of top level domains up to 6 letters (com, net etc) but you want to make that longer or unrestricted.

If there are other special characters you may have at the end of your string, you can add them inside the bracket in the [\w=?]+ component.

Also, if you want it to be case insensitive, you'll want to insert a i between the final / delimiter and .test like so: /i.test
