I think the best way for OpenID Reliers to implement it is to store a cookie with the user's OpenID in it. Then when the user goes to the site, the Relier can fire off a "check_immediate" request. A "check_immediate" request basically asks "Hey, is this user already logged in to their provider, and if so, can I log them in to my site without hassling them?". If Provider answers "yes", the user is logged in without the redirection steps. Otherwise, if the answer is "no", the Relier can proceed with just a normal form-based login.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>This way, we all still have bookmarks that point to "<A href="http://www.sudokular.com">http://www.sudokular.com</A>/", and the bookmarking services can keep track of that single url.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>-Sam</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV><DIV><DIV>On Sep 13, 2007, at 10:33 AM, news letter wrote:</DIV><BR class="Apple-interchange-newline"><BLOCKQUOTE type="cite"><SPAN style="">Dear OpenID enthousiasts,</SPAN><BR><BR><SPAN style="">I have visited some OpenID enabled sites. I have found that they require submitting a form with my OpenID to get the process going. I'm no expert and neither a heavy OpenID user. But I was wondering what would happen if the OpenID enabled website could support adding my OpenID as a request parameter? </SPAN><BR><BR><SPAN style="">Instead of this flow:</SPAN><BR><SPAN style="">1. Http GET request for <A href="http://myenabledsite.com/index.php">http://myenabledsite.com/index.php</A></SPAN><BR><SPAN style="">2. Fill in OpenID in form and click Submit </SPAN><BR><SPAN style="">3. OpenID processing (possibly requiring authentication)</SPAN><BR><SPAN style="">4. Logged in to <A href="http://myenabledsite.com">myenabledsite.com</A></SPAN><BR><BR><SPAN style="">I would get this flow: </SPAN><BR><SPAN style="">1.

OpenID processing (possibly requiring authentication)</SPAN><BR><SPAN style="">3. Logged in to <A href="http://myenabledsite.com">myenabledsite.com</A></SPAN><BR><BR><SPAN style="">I would eliminate step 2 of the orginal process. </SPAN><BR><SPAN style="">I could bookmark my favourite Open-ID enabled sites with the request parameter added, never having to fill in the form anymore.</SPAN><BR><SPAN style="">If I was logged in to my OpenID provider already, I would have a 'true' Single Sign-On experience. </SPAN><BR><BR><SPAN style="">It's hard to imagine I would be the first to think of this and there are probably good reasons not to implement OpenID like this. So I am very curious as to what those reasons are. </SPAN> <BR><SPAN style="">Two, I could think of myself are:</SPAN><BR><SPAN style="">1. that this request parameter would have to be standardised in a way so that users wouldn't have to 'guess' at it</SPAN><BR><SPAN style=""> 2. that you would still have to find out which page to GET with the request parameter. Not all sites 'start' at /index.php. A possible solution for this would be not to use a request parameter but a standard URL. You would be able to login with OpenID to every enabled site at http://<domain>/openid/<your openid>. </SPAN><BR><BR><SPAN style="">Thanks in advance for your feedback.</SPAN><BR><BR>Kind regards,<BR>Robin<BR><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">_______________________________________________</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">user-experience mailing list</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><A href="mailto:user-experience@openid.net">user-experience@openid.net</A></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><A href="http://openid.net/mailman/listinfo/user-experience">http://openid.net/mailman/listinfo/user-experience</A></DIV> </BLOCKQUOTE></DIV><BR></DIV></BODY></HTML>
