Not just maybe, I'd say most likely.
Keep in mind the game client will be totally dumb about it any only append the file name, for example: http://mysite.com/folder/get.phpMyAwesomeTextures.utx.uz (for package MyAwesomeTextures.utx)
Something like

RedirectToURL=http://mysite.com/folder/get.php?file=

will work nicely (assuming the get.php expects the file parameter) as the game client requests URLs such as http://mysite.com/folder/get.php?file=MyAwesomeTextures.utx.uz, which is more likely what you want.
