    IE8 and Forcing Cache Flush??

    On the project that I am currently working, they are using Internet Explorer (IE) 8 because they say "It is the only browser where we can flush the user's browser's cache and prevent them from stealing content. IE8 is the safest way to go..."

    I am blown away by these comments?!

    Then again, I don't really know about the cache part.

    Would someone please educate me on this topic?

    Thanks,


    Debbie

    They are blinded by their own foolishness. That doesn't stop anyone from stealing content, Regardless if you can flush the cache or not.

    Can you help me understand the cache flushing thing?

    I have no clue what they are referring to, and I don't see why Internet Explorer would have some advantage over any other browser?!

    I honestly don't know what "cache flushing" they are referring too...other then what is in the preferences.

    The way they explained it, by using IE8, the application can force the User's Browser's Cache to be flushed...

    I don't know how in the world the server could force a user's browser to do anything, but who knows?!

    My guess is that if can it's a flaw in the browser. In any case as mentioned it won't prevent theft only make it a little less easy.

    And I fail to see how what browser they are using has anything to do with others. Well, unless their goal is to prevent themselves from stealing their own content

    I'll have to ask for more information tomorrow.

    They make it sound like since the application is written in .Net that it can send a message to IE8 and delete all Users' Browsers' Cache from the server.

    I guess they worry that if users store the webpages in their browser's cache that that is a security risk.

    I can sorta see that, but I don't see how the server has the ability to flush the cache on a user's machine?!

    Would this question be better suited in another forum?

    Whether they can do it or not, it's an abuse of the end user to force behavior on them.

    Anyhow, they can't force users to use IE8, which is the important thing ... so it seems like a pretty silly argument anyway. The fact that they themselves are using IE8 is completely irrelevant.

    What a load of baloney !!!!!!!!!!!!!!!!!!!!!!!!!!

    If I want to take an image from the Internet, I don't need it to be cached by the browser at all. I just right click the image and then select save-as and voila . Disabling right click with js is about as useful as an ash tray on a motor bike because I would just turn js off.

    Another quick way to take an image is to click the screen dump key on the keyboard, which copies the screen contents to the clipboard, and then dump it in Photshop (or whatever) and then I can crop and do what I like with it.

    Also, think about it for a minute. What's stopping anyone taking a photo of the screen as a last resort and then edit and enhance the photo of the screen in Photoshop.

    Once anything appears on a user's screen, it is effectively gone if the user wnats it and there is absolutely nothing whatsoever anyone can do to stop the screen contents from being taken.

    If you don't want it to maybe "fall into the wrong hands", then don't freakin' publish it in the first place

    If someone tried to tell me they can stop me from copying anything that appears on the screen infront of me, I would just laugh at them and tell them they have no idea what they are talking about. And it would make no difference what browser and version I am using.
