Hello, We use a security app that sniffs incoming requests to make sure they are still authenticated. If the user needs to be re-authenticated, they are redirected to a login page. Upon successful authentication they are returned to the page of the originating request. Here is the problem, the server side redirect sends the response back to the httpxmlrequest, where the prototype object dutifully inserts it as html. I tried capturing the on302, but for whatever reason this does not get called (httpliveheaders shows a 302, but it never fires on the browser). The cheesy hack I did was to search for some well known text in the response, that I know is only on the login page. If it exists I then do a window. location.reload(), which properly loads the login page. Does someone have a better implementation for this? I while what I did works, it just does not feel right. Thx. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.

I agree that searching the response text is fragile. Perhaps adding/checking an HTTP header would be more consistent? You could use X-JSON, or roll your own.

I have used an Ajax.Responder with on302 successfully, but in Opera the responseText will be blank for anything but 200 so if you need to pass any data use X-JSON or another header. If you are using onSuccess instead of onComplete in your Ajax.Requests then this is a pretty transparent solution, otherwise I recommend you change all onComplete to onSuccess so they don''t get called when they shouldn''t.

Ok, ignorance alert, I cannot find what x-json and how it relates to headers. Can you point me in the right direction?

http://prototypejs.org/api/ajax/request
See the bottom paragraph titled "Evaluating JSON headers". The X-
JSON header is an HTTP header your server sends, whose value is in
JSON form. For example in PHP, you might write:
header(''X-JSON:
{"response":"valid","msg":"All your base are
belong
to us."}'');
As the docs say, "Prototype automatically does so [evals the JSON
header] and passes it as the final argument of each callback (except,
obviously, onCreate)..."
Example:
new Ajax.Request(''/your/url'', {
onSuccess: function(transport, json) {
// Remainder of the code
}
});
