flash - How to check web application status written in Flash/Flex?

Question

I have a typical web application that communicates in the following way:

SWF file makes service calls to Java services (Remote object, over BlazeDS on Tomcat), which in turn communicates to database.

How do I implement a status check service (hosted on another domain) that will check if the ENTIRE app is up and running?

Ideally, I'd make checker SWF that would load App SWF and called its function that would return something from the database (a naive service would count rows in table and hash it with MD5), but security constrains won't let me call loaded SWF's function.

Checking the java services only is not enough, as I am not checking the status of the SWF.

Any ideas?

可以使用特定的查询字符串调用 Flash 网页，这将导致 Flash 加载并发送回状态消息 - 即您通过网页间接调用 Flash。
