flash - Adobe Flex: Why do I get intermittent SecurityErrorEvents on some browsers? -

-

Our Flex app interacts on the TCP-socket connection back to its original server. This requires an allowance from the server and thus we set up one on the host (source code at pastie.org/791060).

It detected Firefox, Safari, Windows and Mac OS X, but then yesterday we found problems with IE 7 on Windows XP. About 50% of cases are raised on a SecurityErrorEvent socket. Security before adding. Despite the call to the load policy file ("xmlsocket: //: 843"), and the overview of transmitting socket policy data to the customer of the Socket Policy server (checked with TCPDump), this error is often reloaded in the flash app in question It can be reversed by the rest, while restarting IE is its return.

Why do we see these intermittent errors, and what can we do about them?

Regarding the issue, a bad socket policy Server implementation is fixed. It seems that it was hanging very quickly in the TCP negotiation with the flash client (did not wait for the string), due to the connection errors in some circumstances, notably in IE7 on Windows 7. I did not know that it was so easy to create havoc at the TCP level at the user level ...

Heath: Thank you for your time. I will keep my own concept of firewall working in my mind because I will definitely face it later because our test progresses.

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
