Workaround : Changing :
desthost=http://backend.example.com
desthost=http://localhost:8081
desthost=http://localhost:8080
to:
desthost=http://backend.example.com:80
desthost=http://localhost:8081
desthost=http://localhost:8080
This was tested and resolved the issue.
Resolution: Engineering recomended the following change :
Add :
com.l7tech.common.http.prov.apache.CommonsHttpClient.enableTrace=false".
to :
/opt/SecureSpan/Gateway/node/default/etc/conf/system.properties
And restart the gateway service.
This was also tested and resolved the issue.
A fix will also be applied in some future version of the gateway.
