Answer 1

Try to set web project's server propery as Local IIS if it is IIS Express. Be sure if project url is right and create virual directory.

Answer 2

When dealing with Uniform Resource Locator(URL) s there are certain syntax standards, in this particular situation we are dealing with Reserved Characters.

As up to RFC 3986, Reserved Characters may (or may not) be defined as delimiters by the generic syntax, by each scheme-specific syntax, or by the implementation-specific syntax of a URI's dereferencing algorithm; And asterisk(*) is a Reserved Character.

The best practice is to use Unreserved Characters in URLs or you can try encoding it.
