Bypass os checking in website

I was checking a website (http://www.shldirect.com/practice_tests.html) but unfortunately it checked my computer and told the operating system is not suitable to access the website.

It was accessable only from Windows or Mac(grrrr… 😡 )
I am using Ubuntu 11.10 and I need to access the site by hook or by crook.

Thinking… Thinking… to spoof my Operating System.

Got an idea :).

I have installed Tamper Data addone in my Firefox Browser (Install it from here).

Start TamperData .

Open The site. It will ask for TamperData (If already started).

Click on Tamper. On User-Agent enter Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0).  and click OK.

Do this action until the page comes. It will tell the website that I am using IE (Product of Micro$oft Window$).

Bingo bypassed the OS Checking. 🙂
