How can i get a flash variable using c# (ASP:NET)?

Hi all,

I have an swf that display some info according with some parameters that i passed throught a cs class. For this in the aspx i have a literal control that I charge in the page_load event (see the code attached).

The idea is that after the swf load completely, it need to have a variable where the user can write what he wants (until here all works fine).

Now the deal is that i need to get in my class what the client wrote in the swf. How can i do this???

Please if someone knows how can i do this it is very urgent.

Thx a lot

Regards,

Daniel Peralta
