WebLogic 12.2.1.4 keeps behaving as if WL-Proxy-Client-Cert is empty even though it's set.
My server is getting SSL traffic incoming from an F5. Attempt to access applications are returning 403s and throw an except "Failed to parse the client certificate in header: WL-Proxy-Client-Cert. Ignoring this certificate.
java.security.cert.CertificateException: Could not parse certificate: java.io.IOException: Empty input".
This is despite the WL-Proxy-Client-Cert showing up both in HTTP debugger logs and if I write it to a log using a ServletFilter. Does anyone know how to fix this?
