Flash and ASP

Hi fellow members.
I have a question which might be tough to answer but i thought i’d try my luck anyway.
I have a website which pulls information from a SQL db and displays it on screen. The thing is, the site has sections for different states in Australia. Ie: list of businesses for victoria, new south wales, etc. Each city has its own table. By the way, it is in ASP.
Now, the problem is that the city selector is in flash. When i click on a city, i’d like to reload the homepage but change the SESSION variable or a global one to the selected city. Is it possible for Flash to send data to an asp page and set a SESSION variable to whatever text the button sends?
Hope i am making sense, and thankyou in advance.
