Rails - Apr 2006 - Issuing an ajax request to a different web server?

Is it possible to have an Ajax request go to a different server than
the one that originally rendered the web page? I am attempting this,
but the ajax server never gets the request.

For example, inside a form:

<%= submit_to_remote(''add_lead'',''Add
Lead(s)'',
                          :url => 
"http://123.456.789.0:3000/users/add_lead",
                          :loading => ''item_loading()'')
%>


which generates the following html:

<input name="add_lead" onclick="new 
Ajax.Request(''http://123.456.789.0:3000/users/add_lead'',
{asynchronous:true, evalScripts:true, 
onLoading:function(request){item_loading()}, 
parameters:Form.serialize(this.form)}); return false;"
type="button"
value="Add Lead(s)" />

Thanks,
Don

Browsers prevent this for very real security reasons. You cannot and should
not even try to do that. If you really need to use a service at another
site, configure the main site to proxy to the other site.

Greg,
  That makes sense. I will attempt to set up the proxy.

Thanks,

You can''t do it through XHR, but that doesn''t mean you
can''t do AJAX.

There are quite a few things that do work across domains - image
references, posts to a hidden iframe, css links, and of course
<script> tags.  Just look at what advertisers have been doing for
quite a while and you''ll get a pretty good idea for what is possible.
