Dynamic Proxy Support

Hi,
Can there be a dynamic proxy support for GCSF? I'm roaming between proxy limited and open networks (ie work & office). When in office, use of proxy is mandatory, no direct access to Google Drive.
But if GCSF supports proxy, could it be intelligent enough to try to direct as well when it can't reach the proxy, and vice versa.
If proxy is set, try proxy, if can't connect, try direct. After given period ie 1 minute, if direct connection times out and is not possible (ie I went to work), then try to connect through proxy. If connected, use it until it times out again (ie I went home), then try direct.

The issue names no files, tests, or entry points. Start by locating GCSF’s proxy configuration and connection retry paths. Done means supporting proxy and direct connections, switching between them after connection failures or timeouts, and continuing to use the working route until it fails.
