Configure the HTTP Proxy to Connect to the Cloud Service
If you want to use the Use proxy to connect to the cloud service option in the Add Cloud Account dialog, you must first configure the HTTP proxy that you want to use to manage EC2 resources.
To configure the HTTP proxy, click the Configure HTTP Proxy toolbar button and enter the HTTP proxy setting information (such as server, port, and user credentials). A test request is sent to the server to verify the proxy setting. Once verified, the proxy setting is saved in the AWS account.
