If this is intended as an improvement of an existing application, then you basically need a Filter which detects “dirty” and “friendly” URLs. When it detects a “dirty” URL, then it should redirect the request to a “friendly” URL by HttpServletResponse#sendRedirect(). When it detects a “friendly” URL, then it should forward the request to the … Read more

There’s no ambiguity here: RFC3986 says no, that is, URIs cannot contain unicode characters, only ASCII. An entirely different matter is how browsers represent encoded characters when displaying a URI, for example some browsers will display a space in a URL instead of ‘%20’. This is how IDN works too: punycoded strings are encoded and … Read more
The slugs make the URL more user-friendly and you know what to expect when you click a link. Search engines such as Google, rank the pages higher if the searchword is in the URL.
There are two steps to solve this problem. First, create a new route or change the default route to accept an additional parameter: routes.MapRoute( “Default”, // Route name “{controller}/{action}/{id}/{ignoreThisBit}”, new { controller = “Home”, action = “Index”, id = “”, ignoreThisBit = “”} // Parameter defaults ) Now you can type whatever you want to … Read more
I like the php-slugs code at google code solution. But if you want a simpler one that works with UTF-8: function format_uri( $string, $separator=”-” ) { $accents_regex = ‘~&([a-z]{1,2})(?:acute|cedil|circ|grave|lig|orn|ring|slash|th|tilde|uml);~i’; $special_cases = array( ‘&’ => ‘and’, “‘” => ”); $string = mb_strtolower( trim( $string ), ‘UTF-8’ ); $string = str_replace( array_keys($special_cases), array_values( $special_cases), $string ); $string … Read more

I recently wrote a URL encoder, so this is pretty fresh in my mind. http://site/gwturl#user:45/comments All the characters in the fragment part (user:45/comments) are perfectly legal for RFC 3986 URIs. The relevant parts of the ABNF: fragment = *( pchar / “/” / “?” ) pchar = unreserved / pct-encoded / sub-delims / “:” / … Read more
To quote section 2.3 of RFC 3986: Characters that are allowed in a URI, but do not have a reserved purpose, are called unreserved. These include uppercase and lowercase letters, decimal digits, hyphen, period, underscore, and tilde. ALPHA DIGIT “-” / “.” / “_” / “~” Note that RFC 3986 lists fewer reserved punctuation marks … Read more
