[jQuery] Re: Cross domain Ajax without Proxy
I tested it and it works cross-domain with IE7 and FF3. It appears to
send the data URL encoded inside the CSS like so:
#cr0 {
background: red url(http://cssrpc/%3Ch1%3EResult%20from%20CSS
%201%3C/h1%3E);
}
#cr1 {
background: blue url(http://cssrpc/%3Cp%3EThis%20is%20lorem%20ipsum
%20in%20a%20paragraph%20tag.%20Or%20something.%3C/p%3E);
}
So the url field is then URL decoded and written to the page. Is this
right? Is there a advantage of using CSS files instead of JS files
for cross-domain data communication?

Hi Bill, it seems that that technique doesn't work for FF3, so it's
out, unfortunately.
It makes reference to an original prototype that does work with FF3, you
can see it work here:

Although it doesn't actually demonstrate loading anythingcross-domain, so I'm
not sure if that would work or not.

AFAIK cookies are stored an a per-domain basis, so if your iframe page resides in the same domain it has access to the same cookies, and only then. If it is in a different domain, then you'll have to communicate via server requests. If it's all under your control, that shouldn't be a problem. There's also a technique where the page in the iframe set's it's window.name property which can be read by the parent frame, but that can be used only once 'onload'. - ricardo

Flash allows you to set cross-domain policies via a file called crossdomain.xml, see here: http://livedocs.adobe.com/flash/9.0/main/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDocs_Partsfile=1085.html But that requires access to the server which will provide the data anyway, so you might aswell implement JSON/XML directly avoiding an extra layer of communication. - ricardo On Dec 11, 3:26 pm, howa howac...@gmail.com wrote: On 12月11日, 上午2時32分, ricardobeat ricardob...@gmail.com wrote: I believe you have already answered that to yourself but was hoping for a misteryous miraculous solution right? :) No, there isn't, you'll have to do it server-side.

[jQuery] Re: Cross domain Ajax without Proxy
Tangent question: 1. If someone was to add an iframe to a page, would cookies be sent to the page within the iframe? I'm working on an app where we need to scrape content from multiple pages that all use a common login scheme that creates a cookie for a central server, despite the application being different domains. I'm trying to find every solution I can, client and server-side... 2. If cookies are sent, I could theoretically fetch the content of the iframe and send it back to the server, yes? stephen On Wed, Dec 10, 2008 at 10:32, ricardobeat [EMAIL PROTECTED] wrote: I believe you have already answered that to yourself but was hoping for a misteryous miraculous solution right? :) No, there isn't, you'll have to do it server-side.
