Flex 1.5 syntax

In Flex 1.5, you added a URL pattern to the whitelist that matched the 

url

 of the 

HTTPService tag.

MXML tag:

<mx:HTTPService id="MyService" url="http://myServer.com/services/my.jsp"/>

flex-config.xml file:

<http-proxy>

<whitelist>

<unnamed>

<url>http://myServer.com/services/*</url>

</unnamed>

</whitelist>

</http-proxy>

Flex 2 syntax

In Flex 2, the MXML tag syntax is almost the same, but you must also set the value of the 

useProxy

 property to 

true

. Flex 2 does not support the 

protocol

 property that was available 

in Flex 1.5; the channel defines the protocol. Flex Data Services uses either the defaultHTTP 
or defaultHTTPS destination depending on whether the URL starts with HTTP or HTTPS, 
respectively.

In the services-config.xml file or a file that it includes by reference, such as the proxy-
config.xml file, you add a 

dynamic-url

 to the 

defaultHTTP

 destination for an 

HTTPService. The URL pattern must match the URL used in the MXML tag.

MXML tag:

<mx:HTTPService id="MyService" url="http://myServer.com/services/my.jsp" 

useProxy="true"/>

proxy-config.xml file:

<destination id="defaultHTTP">

<properties>

<dynamic-url>http://myServer.com/services/*</dynamic-url>

...

</properties>

</destination>
