If you were going to write flash-based RIA, what language would you chose for server?
Any thoughts are appreciated! Thank you in advance!
UPD: Well, let’s say I’m going to write texteditor. Database on server is MongoDB. So it’s likely that client and server communicated via JSON. Serialized blocks of text re astored in DB, so the server gets them from DB and sends them to client or updates them. The major functionality should be on client side. The server also should be able to export documents to TeX format.
Since Flash player 11 and AIR 3 are out, you will be able to leverage native JSON support client side.
Therefore, if you intend to use JSON anyway it does not really matter which server side technology you use. As Rob already mentioned, Java and Php are often used for this purpose.
Keep in mind though that using AMF will have some performance benefits and will allow you to transport typed objects without the need to manually parse them.
