Proxy servers updating
When buffering is disabled, the response is passed to a client synchronously, immediately as it is received.nginx will not try to read the whole response from the proxied server.The maximum size of the data that nginx can receive from the server at a time is set by the proxy_buffer_size directive.Buffering can also be enabled or disabled by passing “ of the buffers used for reading a response from the proxied server, for a single connection.Defines conditions under which the response will not be taken from a cache.If at least one value of the string parameters is not empty and is not equal to “0” then the response will not be taken from the cache: When enabled, only one request at a time will be allowed to populate a new cache element identified according to the proxy_cache_key directive by passing a request to a proxied server.

If there is a firewall in the path, make sure that it's open so that the Connector can make HTTPS (TCP) requests to the Application Proxy.
For high availability purposes, you should deploy at least two connectors. You can confirm that a new connector installed correctly by checking for it in either the Azure portal or on your server.
If the whole response does not fit into memory, a part of it can be saved to a temporary file on the disk.
Writing to temporary files is controlled by the proxy_max_temp_file_size and proxy_temp_file_write_size directives.
