Hello. I''ve been trying this out for the past two days and I can''t seem to get it. I''m going to have a page where you can upload x amount of images at once.

i know someone just recently asked about queueing ajax requests, my question is similar in the regards that i don''t want my application to send multiple requests. i have 2 sortabbles lists left, and right. when i move an item from left to the right the onUpdate callback will send 2 ajax requests. one for each sortables. however. i want it to serialize and send back the results from

This uses an HTTP redirect that goes to the client and returns. Is this an idiomatic way to design the flow in Rails? -- fxn
