Trying to check if a SAML attribute contains a role retrieved from a stringmap (the attribute contains a comma separated list of roles):
HTTP.REQ.USER.ATTRIBUTE(5).CONTAINS(HTTP.REQ.URL.QUERY.VALUE("pageid").MAP_STRING("UrlProtection"))
Unfortunately Netscaler complains: Only constant parameters are allowed for function ["pageid").MAP_STRING, 72]
Any ideas how to get around this?
