Answer 1

Try this regex:

(https?:\/\/[^\/]+)\/(.*)

Group 1 is the first part. Group 2 is the second part.

It works by first finding http:// or https:// followed by a bunch of non-forward-slashes. It puts all that into group 1. Then, it looks for a forward slash. and finally, puts the rest of the string into group 2.

• () is capturing group. The first pair of () is group 1, the second pair is group 2, and so on.
• s? means that the s is optional
• \\/ matches / literally. You can just write / in some flavours
• [^] is a reverse character class. It will match anything except the characters inside it.
• . matches everything except line terminators.
• * means 0 or more times.
