comparison flys-client/src/main/java/de/intevation/flys/client/server/was/Response.java @ 2943:7683d4e43afa
Implement class representation of a Web Authentication Service (WAS)
request and response. If the authentication is successful the WAS
responses with a base64 encoded Security Assertion Markup Language.
The current implementation of the saml response simplifies the protocol
and misses validation.
