Many of our forms use GET. They should be using POST unless there is a great reason not to.
I think the only remaining forms which are improperly submitted using GET are: /save_note (Notes tab on the system page) /save_exclude (Excluded Families tab on the system page) /really_cancel (old job cancellation page) /tasks/disable_from_ui (Disable button on tasks grid) /configuration/remove (Clear Current Value button on config grid) /configuration/save (form on config item page) /retentiontag/delete (Delete button on retention tags grid) /retentiontag/save (form on new retention tag page) /retentiontag/save_edit (form on edit retention tag page) /keytypes/remove (Remove button on key types grid) /keytypes/save (form on new key type page and edit key type page) /osversions/save (form on OS version page)
I'm closing this particular bug, since it is something which will be fixed eventually by moving to back bone and a REST api. Implementing API endpoints and using Backbone will make it much harder to use GET instead of POST (perhaps it's not even possible).
