To support requesting data from external sources via the internet, some proxy servers may require specific credentials for access. To support this configuration, the TT .NET SDK requires access to the user’s proxy credentials to make the required requests.<\/p>\n\n\n\n
Note<\/strong>: In order to connect to a proxy server that requires credentials, you must configure a ProxyCredentialsHandler<\/a> when creating your application.<\/p>\n\n\n\n When connecting to a proxy server that requires credentials, the TT .NET SDK requests the credentials from the application via the ProxyCredentialsHandler<\/a>. The credentials provided by the application will be handed to the proxy which, if valid, should allow the TT .NET SDK to access the external internet resources.<\/p>\n\n\n\n The ProxyCredentialsHandler<\/a> defined in the TTAPI object provides the mechanism to pass proxy credentials to the SDK. When creating your application, configure the handler and pass it into the CreateTTAPI method.<\/p>\n\n\n\n Note<\/strong>: This is an optional handler and may be omitted if the application does not need to support proxies that require credentials.<\/p>\n\n\n\n The following code snippet demonstrates an example of this process.<\/p>\n\n\n\n<\/a>Configuring the ProxyCredentialsHandler<\/h2>\n\n\n\n
