Immediate HTTP 504 error from OpenID endpoint when specifc realm/return_to parameters are used
I am seeing an issue where Yahoo! returns an HTTP 504 error when the openid.return_to and openid.realm parameters are set to specific value (example:namespace.accesscontrol.windows.net), but not when they are set to a different value (example: namespace2.accesscontrol.windows.net). If the user is not already logged into Yahoo!, the 504 error gets returned immeditately, and it happens intermittently (over 90% of the time).
Can someone advise on why this occurs? It appears that Yahoo! may be throttling the response to the URL with the specific realm/return value .
Please it is not right http 504 error need to released this no good and please openid relam/return to parameter are used Yahoo! Need to resetting to openid with browser .just remove http 504 error still working on mozilla personal which was Yahoo! Openid? We like to improve user experience by prefilling in a username.could u let us know how we could sdo somethinglike that?
