partial-assertion-saml-data-http-header

I viewed the responses to this question.

 

https://devcentral.f5.com/questions/manipulate-saml-assertion-data

 

The irule in the response does work but it seems to send ALL of the saml session in http headers and I get an HTTP Error 400. The size of the request headers is too long. response from the server. Does anyone have an example irule that has assertion of partial data specifically just friendly name saml attributes. The stuff in the session.saml/Common/{Policy}_act_saml_auth_ag.attr.friendlyName section
