In this same vein, I am curious what you guys think of using semi-colon and comma characters in URLs when pointing at an endpoint that generates a response that would typically be provided by a query string, e.g.:

    http://site.com/generate;lang=en,size=32,weight=78

RESTful Web Services Cookbook[1] gave me the idea (a fantastic book) and what I like about it, is that interstitial proxy software seems to molest the URL less where as some refuse to pass through query string params for some reason (e.g. CloudFront).

Anyone see any glaring issues with this?
