URL

|
|
Description |
A simple but powerful URL validating regex. Accepts multiple sub-domains and sub-directories. Even accepts query strings ande ports! Accepts HTTP or HTTPS. Also accepts optional "/" on end of address. This may be the mother of all URL regexes. It's much more stricter than most others that do far less.

Absolute Path
|
|
Expression |
^((?:\/[a-zA-Z0-9]+(?:_[a-zA-Z0-9]+)*(?:\-[a-zA-Z0-9]+)*)+)$
|
|
Description |
An overly simple UNIX based path regex. The path must begin with a forward slash. The path segments may not lead or end with an underscore or dash which is a good thing. They also can not be doubled (__ or --). Another good thing. I've omitted all the punctuation that RFC allows until further notice.
