Hi Lifters,
How would you feel about renaming .scala files to match the main class/trait
in them?
Let me give you a few examples,
lift/src/main/scala/net/liftweb/http/auth/Authentication.scala
currently holds a trait named HttpAuthentication.
I'd like to rename it HttpAuthentication.scala
State is maintained on the app server, not pawned
off to some other place. This leads to better scalability characteristics.
The developer deals with higher level abstractions than dissecting the HTTP
request and reconstituting state.

I have been reading about Lift Authentication and the Authentication

Is it possible to inspect a request to perform authentication before sending
the 401 if a user is not authenticated?
We use an authentication server

I think that it's a good idea. I actually like the Java convention of
naming the source file after the main class for the reason you mention
Please don't shoot me for bringing this up again. I still don't think
the current behavior of Menu.item makes sense. If the user doesn't
want that link to appear on the page, then they shouldn't include
lift:Menu.item name=foo1 / in its source. Most people put text
around their link:
So, are the sessions replicated or do you lose active connections if a node
goes down?
I agree I don't have a problem with server session state ... the only
problem I have is we originally used JSF for a number of our applications

Chad,
We have HTTP Basic Auth and HTTP Digest Auth support in Lift. The
authentication is implemented as a partial function that you implement
like so:
LiftRules.httpAuthProtectedResource.prepend {
case (ParsePath(api :: _, _, _, _)) = Full(AuthRole(admin))
}
Hmm - Im a little skeptical. One of the nice things about Scala is
that you don't need one source file per class... that really bugs me
about Java.
Can you be suscint about what stuff your splitting. Right now the
codebase in lift feels workable. I wouldnt want to see it split out
into a jillion
Further to that example, no doubt someone will laugh at me for using
database access on each request... However this is just an example! In
reality I actually read from an LRU cache to save the database access.
Cheers, Tim

You're talking about JAAS, right? I think that the term form-based
authentication is a bit ambiguous. For those that aren't familiar, the EJB
server can use an application-provided form and authtentication callback to
go against an existing JAAS auth module.

Nice. I ran the command line that you specified and the run is closer to 10

Hi,
Everything said here pretty much covers it. I just want to say the
HTTP authentication has pretty much nothing to do with form based
authentication. Lift HTTP authentication is based on RFC 2617. Form
based authentication is something invented by J(2)EE JSR specs and J(2)
EE containers use
Further it's my understanding that the current crop of Scala books
assume you already have a working knowledge of java.

Programming in Scala is not for absolute-never-programmed-before
beginners, but you don't need to know any Java to use it. You'll
