Re: [undertow-dev] AuthenticationMechanismFactory

There are a few major advantages. Now all an extension does is register the factory, and the user can enable it in web.xml (or jboss-web.xml) using whatever options they want, in whatever order they want. If an extension really wants to completely override the auth mechanism it can still do that, by simply clearing the auth mechanism list and adding the name of its mechanism instead. Basically before there was no real way for extensions to play nicely with each other. Undertow has the ability for multiple authentication mechanisms to work correctly together, but with the old way there was no reliable way to actually use this with custom authentication mechanisms, as there was no way to specify order.Custom mechanisms would also need to have a custom way of configuration, e.g. reading options from a separate file. Now custom mechanisms work exactly the same way as the standard mechanisms, it is easy to specify the order, it is easy to configure any properties that may be required, and no functionality has been lost, as an extension can still override auth mechanisms if that is the intent. The fact that not all methods may use the form data parser is irrelevant, some methods will and so it is provided. Stuart ----- Original Message -----
