webscrapping with javascript protection -- 3

Hello, I need help in web scrapping this page: [login to view URL] the website has some javascript protection. that sets a cookie "bm_sd" to be able to browse the website. without that cookie.. any requests to the website gets a response: "429 too many requests" I want help in figure out what is the function doing that, so I can simulate it in (HttpWebRequest C# or curl in php or HttpURLConnection in java) that doesn't support javascript. (Without Browser just basic requests) DON'T BID if you can't bypass that javascript protection!. Answer 4 x 5 = ? in top of your bid. Thank you.
