I sometimes run into problems on TransSee where my system to automatically download GTFS files with libcurl fails because the web server hosting it is blocking it.
Two of the reason this happens is because the web server only allow actual browsers to download files and because I am blocked from downloading it because they are excluding access to IP addresses other then ones in the United States from accessing it. I am in Canada.
This change addresses this by adding best practices advising against this.
