URL fragment lost as part of SAML token authentication; workaround / standard pattern?
问题 Several web application authentication protocols (like WS-Federation and the SAML protocol, i.e., so-called 'passive' protocols, and apparently also ASP.NET Forms authentication, see this StackOverflow question, and AppEngine, see this GWT bug comment) lose the original 'URL fragment', i.e. the part after the #-sign. What happens is roughly the following: in a clean browser (so no cached info/cookies/login information) I open URL (1) http://example.com/myapp/somepage?some=parameter#somewhere.
