Hi, I added ZnUrl>>#withRelativeReference: which implements the process described in section 5 of RFC 3986.
https://pharo.fogbugz.com/f/cases/14855/Add-reference-resolution-to-ZnUrl Summary: In certain contexts (like links on a webpage) partial URLs are used that must be interpreted relative to a base URL (like the URL of the webpage itself). Example: 'http://www.site.com/static/html/home.html' asZnUrl withRelativeReference: '../js/menu.js' => http://www.site.com/static/js/menu.js This was previously not possible with ZnUrl. If you know this stuff, please have a look. Monty ? Peter ? Sven PS: this is in #bleedingEdge for now
