Flash Player did not cache the SWZ files

Hi,

     I am usig the Flex 4.1 to create my Applican, and to reduce the size of the application.swf I sat the framework linkage to RSL, which produce a small swf file.

     and as what I read about the RSL the client will download the SWZ files at first time and cached them to be used, but I faced an issue with Flash Player 11 where the        swz files did not get cached and the application download them each time. so please advice about it, and is this related to the version of the Flash Player?

     these are the files Names textLayout_1.1.0.604.swz,textLayout.swc,framework_4.1.0.16076.swz,fra mework.swc

      here is how I added the links in the flex-config.xml.
