307ADOBE FLEX 3
Building and Deploying Adobe Flex 3 Applications
Types of network access
Deployed Flex applications typically make several types of requests to services within your firewall, as the
following example shows:
Most of the deployment issues that customers report are related to network security and routing, and fall into one
of the following scenarios:
1 Direct access to resources on a web server, such as image files. In the preceding example, the client directly
accesses resources on webserver.example.com.
2 Direct access to resources on your application server. In the preceding example, the client directly accesses
resources on appserver.example.com. Ensure that deployed Flex applications can access the appropriate servers.
3 Web services requests through a proxy. A proxy redirects a request to the server that handles the web service.
In the preceding example, the client accesses a resource on appserver.example.com, but that request is redirected
to finance.example.com. Ensure that you configure the proxy server correctly so that deployed Flex applications
can access your web services, or other data services, through the proxy.
