"""
This test ensures that Wget handles a 504 Gateway Timeout response
correctly.
Since, we do not have a direct mechanism for conditionally sending responses
via the HTTP Server, I've used a workaround.
The server will always respond to a request for File1 with a 504 Gateway
Timeout. Using the --tries=2 option, we ensure that Wget attempts the file
only twice and then move on to the next file. Finally, check the exact
requests that the Server received and compare them, in order, to the
expected sequence of requests.
In this case, we expect Wget to attempt File1 twice and File2 once. If Wget
considered 504 as a general Server Error, it would be a fatal failure and
Wget would request File1 only once.
