How calculate a facebook post parameter

Hi Experts, when we login on facebook, the login form post a parameter called "qsstamp". The value of this parameter is calculated by a javascript, something like this: 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

I could not figure out how this value is calculated. Could someone help me?

Thanks
Alexandre

that is a proprietary algorithm they are using.  that's like asking whats the secret ingredient in a recipe. Highly Highly doubtful your going to find that algorithm :(

I would recommend that you start here with the faceBook API and SDK

But this value is calculated on the client side?

The value is more than likely caculated on the client side after making calls to the Server
my apologies for my communication being unclear.
 after running  through the SDK and API it doesn't look like They  reveal how that algorithm is calculated.
