The LocalConnection class lets you enable communication between two different SWF files or Flex applications. The LocalConnection class can also be used to establish communication between SWF files created using an old version, such as ActionScript 1.0 or 2.0, and vice versa. Using LocalConnection, you can only communicate among SWF files that are running on the same physical computers, but they can execute in different applications (for example, two SWF files running in two different browsers or two different Flash Player instances).
For every LocalConnection communication, two SWF applications are involved. They are commonly known as a sender SWF file and a listener (or receiving) SWF file. You can easily communicate with two SWF files using LocalConnection if they are hosted in the same domain. For example, www.domain1.com/app1.swf can communicate with www.domain1.com/app2.swf using LocalConnection without any security concerns.
