if sv_downloadurl site does not have the map for fast dl then get bot to automatically upload request map file onto site so you can fast dl.
i am sorry to tell you this but this is not possible =(
first off something like this is kinda messed up
second of all if the person were to go for fast dl and the server does not have it the user will exit and by the time the bot has uploaded to your site, your sv_downloadurl will be useless because everyone will have been redirected to download from the server because the sv_downloadurl site has reported that it either A.does not have the map or B.has partial which returns the error of redirect to server.
nice try, and don't use translators to change your language makes everything sound stupid
phony=fake, but translator doesnt know the difference
