Error on Karaf (Predix 14.3) - 413 FULL head - 413 (Request Entity Too Large)

Question

I have the following architecture

BROWSER <-> Play Framework 2.2.1 + AngularJS <-(REST)-> Karaf

and it works; when I introduce

BROWSER <-> Apache Revere Proxy <->Play Framework 2.2.1 + AngularJS <-(REST)-> Karaf

it works; when I add OpenID authentication

BROWSER <-> Apache Revere Proxy + OpenId Module <->Play Framework 2.2.1 + AngularJS <-(REST)-> Karaf

I get on the browser

Failed to load resource: the server responded with a status of 413 (Request Entity Too Large)

on the play framework log

Request DefaultHttpRequest(chunked: false) GET /service/connectc/command/prototypes/null HTTP/1.1 Host: URLXXXXXXXXX:9090 uid: XXXXXXXX ge_gessocompanyname: Company sm_first_name: Giacomo Cookie:......

Response DefaultHttpResponse(chunked: false) HTTP/1.1 413 FULL head Content-Length: 0 Connection: close Server: Jetty(7.6.8.v20121106)

XXXXXX=url and my id name

Indeed the authentication module introduce a very big header with Authentication token, SAML, Cookies etc...information

any suggestion?

UPDATE: it seems an error of Karaf

Answer 1

I solved the issue enabling HTTPS protocol on KARAF; indeed the HTTP header is too small to host authentication (SAML) header.
