Regex pattern for domain-part of URL

Question

I am looking for a regex-pattern that matches the domain path of an url (http or https)

example 1:

 https://www.blabla.com/path/pic.jpg

should match

 https://www.blabla.com

example 2:

 http://my.domain.tld/directory/?something

should match

 http://my.domain.tld

Are you using a programming language (which?) or a tool (which?)? Many languages provide built-in functions to parse URLs. — Martin Ender

@m.buettner yes i am using actionscript which afaik does not have an URL class but has a RegEx class. — clamp

something along the lines:

#^(https?://[a-z0-9.-]+)(?=/|$).*#i

It depends of course which characters you'd like to allow in the domain name.

P.S. # are there to delimit the regex, i at the end indicates case-insensitivity.

@silentghost Greets! can you explain the - 'function' in the regex? Thanks

@JosephMarikle: that's just to delimit the regex, there was no indication which flavour clamp was using when I posted my answer. Besides, I'm not familiar with details of actionscript regex syntax.

@cl-r: experts-exchange.com ? Not sure I understand your question otherwise.

@cl-r it's a character class (brackets indicate a character class) that includes word characters (\w), periods (.), or dashes(-)
