I can't say anything regarding FDS, but from my experience with HTTPService, you can pass what you would call hidden variables by simply adding them to the request using Actionscript, just before sending the request to the server. You can modify the request parameters like you would when adding properties to an object.
Handling exceptions is rather simple, much like Java in that respect. You should be able to just use simple try catch blocks. Checking the LiveDocs should help if you get stuck. Session handling is a bit tricky, but you can handle most of it through Apache or IIS. Flex retains the browser's session state, as far as I can tell, when using HTTPService. We've used HTTPService to authenticate on a user's cookie before returning our XML data. The trick is that Flex has to request and retrieve the session data through another script. It isn't aware of the session variables at runtime. Hope that helps, - William --- In [email protected], "siva.flex" <[EMAIL PROTECTED]> wrote: > > Hi All, > > I have developed prototype .
