I need a Python script, designed to run on a Unix box (Ubuntu) that will submit a POST form to a server, and maintain a connection to that server while it does 'push' updates, ultimately sending a .zip file when the server has finished its work. This is designed to automate a download process from the [url removed, login to view] servers. The script should have a settable 'time out' to allow graceful failure if the USGS server fails to deliver a .zip file. The major trick to this file is the use of sockets or other Python technology to keep the connection to the USGS server open. The USGS server is using some sort of server-push technology to update a web-browser with status reports until the .zip file is ready for transmission. The POST form is attached to the bid request. Psuedocode: Send POST form to USGS Server Maintain open connection to USGS Server Do Receive update messages from USGS Server Until .ZIP is ready or Timeout occurs If ZipReady Download .ZIP file when sent from USGS Server ***NOTE: The USGS server is not terribly reliable, if it takes more than 15 minutes for a .ZIP to be ready for download, try again later for your testing. The extraction can take a LONG time.***
