I need to do the validation for the URL

"https://myapp.com/mycompanyname/"
There mycompanyname is mandatory , It can be any name. I tried the below code:

"is not validating" is not informative.
Show examples of url that will match and some that don't.

This will accept "http://www.com" which is not valid url.
And it will also accept single or more then W in any url like "http://wwwww.test.com"

Here is a link to RegEx documentation:
perlre - perldoc.perl.org[^]
Here is links to tools to help build RegEx and debug them:
.NET Regex Tester - Regex Storm[^]
Expresso Regular Expression Tool[^]
This one show you the RegEx as a nice graph which is really helpful to understand what is doing a RegEx:
