One test webserver, with the following applications
service.ganymedes.com:8008 - WCF RESTful service, basically the FormsAuth sample from WCF Starter Kit Preview 2
mvc.ganymedes.com:8008 - ASP.NET MVC 2.0 application
web.config for service.ganymedes.com:
<authentication mode="Forms">
<forms loginUrl="~/login.aspx" timeout="2880" domain="ganymedes.com" name="GANYMEDES_COOKIE" path="/" />
</authentication>
web.config for mvc.ganymedes.com:
<authentication mode="Forms">
<forms loginUrl="~/Account/LogOn" timeout="2880" domain="ganymedes.com" name="GANYMEDES_COOKIE" path="/" />
</authentication>
Trying my darndest, a GET (or POST for that matter) via jQuery's $.ajax or getJson does not send my cookie (according to Firebug), so I get HTTP 302 returned from the WCF service:

It's sent when mucking about on the MVC site though:

I also put the exact same settings in both applications' web.config files (self-generated validationKey and decryptionKey).
