Hello,



I'm looking for some advice on which way to approach the following...I need 

to validate that a user's entry on a form is a web site address, 

ie..www.p2p.wrox.com. I know that you can use the javascript indexOf() to 

find the "@" when validating an e-mail address, but what would I look for 

in regards to a web address? Left(document.form.webaddress.value, 3) and 

check for the www? Any input would be greatly appreciated. Thanks.

not all web addresses have www



e.g. http://p2p.wrox.com



The only thing I can suggest is to get a full list of domains

(.com,.net,.co.uk etc) and check the string ends with one
