Title: Missing backslash in javascript

Firefox 3.0 threw up a warning about this expression that it had unterminated parentheses. As near as I can determine, the final forward slash should be escaped. So it should look like this: ^http\://[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?$

Thanks! To use it with php, I had to add a "^" at the very end, to stop php complaining about a "missing end delimiter": preg_match( "^http\://[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(/\S*)?$^", $value ) sweet :)
