We've struggled with this issue *a lot*. Here is our final solution that seems
to have resolved the issue in a satisfactory way:
1. Our build environment renames the SWF to myapp_1_2_3_4.swf where 1.2.3.4 is
the current version number.
2. We define a variable at compile time that specifies the SWF version number
FlexBuilder: -define+=MYAPP::SWF_VERSION,'0.0.0.0'
Ant XML: <define name="MYAPP::SWF_VERSION" value="${SWF_VERSION}" />
Ant CMD: ant -DSWF_VERSION='%3' -f build.xml MYAPP
AS Code: var SWF_VERSION:String = MYAPP::SWF_VERSION
note: '%3' is a command line argument to a batch script that is called
by our build environment.
3. At load time, MYAPP.SWF makes a request to the server to get the expected
version of the SWF. If the value of SWF_VERSION does not match the version
returned by the server, we show an error that asks the user to refresh the
browser after clearing the cache. We also have a URL parameter,
skipVersionCheck to bypass the check if necessary, and we allow 0.0.0.0 as our
version number for debug builds.
