Hi all, In the book RESTful Web Services[1] (from O’Reilly) there’s a little section about URI design where it tells you to use “semicolons” or “commas” to separate pieces of information at the same level. For example, suppose I’ve got a Message resource and I wanna take all the messages between two dates: ‘/messages/2007-12-01,2007-12-10’. Does exist any “canonical” way to achieve this in Rails 2? Thank you in advance. [1] [http://www.oreilly.com/catalog/9780596529260/](http://www.oreilly.com/catalog/9780596529260/) ---

You can define routes like: /foo/:date1/:date2 and map it to ur controller and action. I don’t think it is possible to separate them by comma Sent from my iPhone On Dec 12, 2007, at 11:56 PM, “Imobach Gonz�lez Sosa” \ **Author:** ![Imobach\_GonzSSSSlez](https://www.ruby-forum.com/letter_avatar_proxy/v4/letter/i/bbe5ce/32.png) [@Imobach\_GonzSSSSlez](https://www.ruby-forum.com/u/Imobach_GonzSSSSlez)\ **Post date:** [December 15, 2007, 7:56pm UTC](https://www.ruby-forum.com/t/colons-and-semicolons-in-rest-uris/122988/3 "2007-12-15T19:56:16Z") Thank you.
