Hi Rick!
Thank you for your response!
I am thinking in sending the entire information (order header plus its details) all on the end of the process. During the user's manipulation, I don't send large amounts of data to the server (only normal ASP updating). My doubt is about the nature of the solution I'm thinking on. Does it seem to you it's feasible (I mean, to send a XML string with header+details once on the end of the order insertion)?
Thanks!
