I am going to be making an online single player browser game. The online element is needed so that a player can login and store the state of their game. This will include things like what buildings have been made and where they have been positioned as well as the users personal statistics and achievements. At this point in time, I am expecting all of the game logic to be performed client side

So far, I am thinking I will use flash for creating the client side of the game. I am also creating a MySQL database to store all the users information.

My question is how do I connect the two. Presumably I will need some sort of server application which will listen for incoming requests from any clients, perform the SQL query and then return the data.

Does anyone have any recommendations of what technology/language to use?
