How to enable proxy using azure::storage?

Question

azure::storage provides a class operation_context which has set_proxy() and set_default_proxy() methods. However, I could not find any info on how to use it.

For example, how do I make sure that a cloud_blob_client created afterwards will use the operation?

I'm assuming that the static version of the method (i.e. set_default_proxy()) will affect all instances of operation.

Will all cloud_blob_client instances use it?

Usage of web::http::client::http_client with proxy is more obvious. I can use the following code to configure the client with a proxy:

http_client_config config;
config.set_proxy(web_proxy(web_proxy::use_default));
http_client(uri, config);

Answer 1

set_default_proxy() worked for me as long as web_proxy was configured with a proxy address. That is, web_proxy::use_default and web_proxy::use_discovery did not work although I had proxy settings defined for current user on Windows.
