[xwiki-devs] Authentication and SavedRequestRestorerFilter

Hi all and Sergiu in particular, I need a more flexible as well as new kind of authentication for my xwiki farm, I have therefore started a review of the current implementations (which is not really nice), as well as patch proposal (stackable auth and iopen)... I am currently puzzled by the introduction of the SavedRequestRestorerFilter in 10525 (1.5M2). When I apply the selenium test case provided on earlier version (1.4.1), I do not found any issue, and I there wonder what is the use case of this fix ? It seems to me useless in regards to the current state of the authentication code. I have also remove it from my test build, and I see no regression. Does anyone have a test case that shows the usefulness of this ? TIA. Denis
