Scenario: Server is glassfish with jax-ws web services and clients is php based
What type of authentication for web services is more computable with php based clients?
Description:
No. 1 over HTTPS is most compatible, easy to implement in PHP. Don't use #1 over clear HTTP.
Don't know what you mean by No. 2 and No. 3, they sound the same to me. That can be done with curl.
No. 4 is also supported in CURL.
