Authentification & session

[Th Templ]

Hello,

I try to make an authentification of an client of my webservice ( developped with Axis ) whatever the client ( axis or other ).
I want too to keep information about the authenticated client for an other request that he will make later ( check the client is authenticated and have rights to do a task ).
How can I do that? Where can I find documentations or tutorials about it?
Thanks for your help
Templth
