Ajax Callback and Security

[Gazley]

Hi there,

Just wondered whether anyone could explain something for me?

I am building a page that renders a gallery of images specific to a user who has previously logged in. If the user interacts with an image on the page eg., Likes it, Hides it etc., I want to make an Ajax callback to update the image status on the server. Here's the real question(s):

1) Using jQuery Ajax, will the targeted page/URL still be able to "know" the currently logged in user?

2) I want to send data about the image and what has been done to it by the user. Is Json a good candidate for this? Is there a "best" way to build Json "client side".

Many thanks.
