I have a ZnUrl subclass MailtoUrl. It was working for simple cases, but then I realized that ZnUrl assumes a single username. At first, I figured maybe mailto was such a specialized case that it wouldn't be worth reexamining, but then I noticed that ZnUrl implemented #mailToAddress so I figured it was at least worth asking about.
The reason it seems important to specify the users this way is that, although the rfc [1] allows users to be specified in the query, it also says that "[that] form is NOT RECOMMENDED because… some existing clients ignore "to" <hfvalue>s." 1. https://tools.ietf.org/html/rfc6068 ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html
