asp.net mvc dataannotation validating url

Question

can some one tell me how can i validate a url like http://www.abc.com

Answer 1

Use a regular expression data annotation, and use a regex like:

http://www\.\w+\.(com|net|edu|org)

Depending on what you need to validate; are you requiring http: or are you requiring www.? So that could change the regular expression, if optional, to:

(http://)?(www\.)?\w+\.(com|net|edu|org)
