You'll notice
Very long proxied requests can now skip the HTTP client's own timeout when a longer timeout is requested
What
Two internal network request helpers now disable the underlying HTTP client's built-in timeout whenever the caller asks for a timeout longer than 300000 milliseconds (5 minutes). Previously, the client's own timeout could still cut the request short even when a longer timeout was requested.
Why
This lets requests that are meant to run for a long time, such as slow or heavily proxied operations, actually run that long, instead of being cut off by a timeout mechanism the caller never intended to trigger.
