    First, have to say, I'm really not a programmer, have just done a course or two at Uni (a long time ago) lol. I'm developing a website that displays graph and obviously have choosen flash based graphing.

    The data being passed in is dynamic, if I change the data on another page, then go back to the flash report page, 90% of the time the graph does get refreshed. I can live with that, so everything worked quite well until my users want to have SSL enabled.

    Under SSL, the flash graph would NOT get refreshed 90% of the time. It seems that if the browser is closed, the flash graph will get refreshed, but if I just surf between the pages, it would not.

    This is a problem in IE6, IE7, but not in Firefox.

    The header has already got "no-cache" in it.

    I'm really desperate on this, the deadline is just around the corner and all :(

    Any suggestions anyone could give, it would be much appreciated.

    Thanks

    Grace.

    Try adding a random number to the end of the location of your xml / data file file. IE has some bad caching issues and does not behave as it should.

    So, if you previously added the data location like:

    so.addVariable("datasource", "http://some.server/some.xml");

    add the "random" number to fool IE into thinking it is a new file on every view like:

    so.addVariable("datasource", "http://some.server/some.xml?random=" + new Date().getTime());

    This will end up adding the current milliseconds to the end like: http://some.server/some.xml?random=345756490


    This should soplve you issues.

    Hi Aran, thanks for your tip. I made a change based on what you said. The problem still persists, so I'm not sure if I implemented it right. I've copied the relavant section in the two files it generated, could you check it for me please?

    First time
    <param name="movie" value="/charts/charts.swf?&library_path=/charts/charts_library&xml_source=/graph/graph?params_string=1180612800.0_1183204800.0_1_300_false_&rand=-965153224"></param>

    Second time
    <param name="movie" value="/charts/charts.swf?&library_path=/charts/charts_library&xml_source=/graph/graph?params_string=1180612800.0_1183204800.0_1_300_false_&rand=-964854330"></param>

    Thanks a lot

    Grace.

    Hmmm...

    Have you tried specifing an absolute path for your xml source? I am unsure what library path does, but if that is a call to the server, then absolute that path too.

    Also, are you calling the data source through SSL protocol? Unless you specify the https:// in the path to the server in the addVariable() / flashvars, I don't think flash will be calling it securely. Perhaps IE's security model is blocking something ?

    As you can tell, I am just logically going through all possibilities of what could be the issue. Without seeing the page itself I don't know what else to suggest right now. Anyone else?

    The randomisation looks like it is working as intended (although the - in front of the value is a bit strange. Is you server clock set correctly ?)

    Hi Aran. It all works now, we put the randomisation at the end and also changed it to uniqueID instead of Rand, and it worked like a charm.

    Gosh, that was a major crises over, our launching date is next Monday. Thanks so much for your help. Sometimes, I'm really attempted to put "Who Stole My Money prefers Firefox" on our website :)
