I'm running Federation, and I have to configure manually the relay state variable. Is RelayState case syntax case sensitive as I would write it relaystate or should I respect exactly the case ?
I've tried to set it as "relaystate" and the parameter isn't detected and thus ignored.
Yes, the parameter is case sensitive and follows RFC 3986
RelayState
Indicates the URL of the target resource at the Service Provider. The RelayState value should be URL-encoded. By including this query parameter, it tells the IdP to redirect the user the appropriate resource at the Service Provider. This query parameter can be used in place of specifying a target URL when configuring single sign-on. The RelayState query parameter name is case-sensitive, and the value must be URL-encoded
6.2.2.1. Case Normalization
For all URIs, the hexadecimal digits within a percent-encoding
triplet (e.g., "%3a" versus "%3A") are case-insensitive and therefore
should be normalized to use uppercase letters for the digits A-F.
When a URI uses components of the generic syntax, the component
syntax equivalence rules always apply; namely, that the scheme and
host are case-insensitive and therefore should be normalized to
lowercase. For example, the URI <HTTP://www.EXAMPLE.com/> is
equivalent to <http://www.example.com/>. The other generic syntax
components are assumed to be case-sensitive unless specifically
defined otherwise by the scheme (see Section 6.2.3).
