Advanced Settings Page
The Advanced Settings page of Azure Blob Storage Connection Manager allows you to specify how you want to configure the proxy server.
- Proxy Server Settings
-

Using the Proxy Server option, you can provide a proxy server to connect to Azure Blob Storage.
- Port

The Port option allows you to specify the port number of the proxy server for the connection.
- Username
-
The Username option allows you to specify the proxy user account.
- Password
-
The Password option allows you to specify the proxy user’s password.
Note: Proxy Password is not included in the Azure Blob Storage connection manager’s ConnectionString property by default. This is done by design for security reasons. However, you can include it in your ConnectionString if you want to parameterize your connection manager. The format would be ProxyPassword=myProxyPassword; (make sure you have a semicolon as the last character). It can be anywhere in the ConnectionString.
