Hi Florian,
one way to solve your original problem might be (we used this before) is to make the file folder not accessible by the web, but just by the RestXQ stack and instead of directly accessing the file providing a RestXQ function which will retrieve the file, based on your user authentication.
I am not sure about accessing jetty session variables from within the RestXQ stack. I'll have to check on this, if and how it can be achieved.
You can not parallelize update queries, you will never be able to do that in an ACID-compliant database. It would always be possible to corrupt data with concurrent updating queries. However, locking is based on database-level, so you can write to different databases at the same time.
Cheers, Dirk

Hi,
that's the way I have realized the login before, but now I combine this with the http basic authentication, because otherwise you can download all files in the webapp directory without being logged in. I have realized it in that way, but now I can't get the username of the user who is logged in. Is there any way to read the "org.eclipse.jetty.security.UserIdentity" attribute in the session? I always get an error:
HTTP ERROR 400
Problem accessing /restxq/getSession/org.eclipse.jetty.security.UserIdentity. Reason:
Stopped at D:/Projects/******/basex77/basex/webapp/restxq/utilities.xqm,35/18:
[BXSE0002] Stored attribute cannot be retrieved: SessionAuthentication.
Stack Trace:

Powered by Jetty://
The server stops at the line, where it tries to read the session attribute "org.eclipse.jetty.security.UserIdentity".
Another question: Is there any way to realize parallel update queries in baseX?
Cheers,
Florian

Hello Florian,
you might want to ask this question on the jetty mailing list as this seems to be not really specific to BaseX. You most likely also will get a more useful response as we are no jetty experts per se.
However, I also couldn't find any HashLoginModule in our default jetty.xml (and I did a quick google search and could find anything), so I am not really sure what you actually do. Might be useful to post the relevant part of your jetty.xml.
Btw, in our RestXQ-based applications we mainly use application-defined authentication, i.e. we first check the proper login within each output function, so something like:
if(not(_:logged-in())) then () elsewhere _:logged-in() is simply
declare function _:logged-in() as xs:boolean { boolean(_:id()) };and we set the session variable during login.
Cheers,
Dirk

Hey,
I have a problem with the jetty authentication. I use the
HashLoginModule, which is configured in the jetty.xml. The problem is,
that I find no way to write the username in the session, so after
login I have no username to deal with. Has anyone solved the same or a
similar problem? Or are there any tips how to implement a secure
login, after that I can use the entered username in the session?
regards
Florian
