Yes, it is quite unfortunate that PHP makes it hard to access multiple values. It is not impossible or terrible hard though. A helper function in the PHP libraries can provide the needed functionality. You can use either HTTP_RAW_POST_DATA or reading from php://input, this gives you the url encoded list of parameters. Parsing this is trivial. I would guess that there is a work around for Ruby on Rails as well. The core protocol can disallow duplicate parameter names, but I think it should allow extensions to do that. Not sure about pass through parameters. > > I agree that the language in the specification should be clarified so > that the sort order is fully explicit.

Also, the spec should make it clear that duplicate parameter names cannot occur. _______________________________________________ specs mailing list specs@openid.net http://openid.net/mailman/listinfo/specs
