IE Security Warning with QuickTime Object tags

I just received a bug report about the infamous Internet Explorer Security Warning for one of the pages in our application that serves video content over HTTPS.

After viewing the source I found the offender which turned out to be the codebase attribute set to http://www.apple.com/qtactivex/qtplugin.cab.

<object id="videoObject" classid="clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B" 
            codebase="http://www.apple.com/qtactivex/qtplugin.cab" 
            width="330" height="292"> 
            <param name="src" value="https://securedomain/video.mp4" /> 
            <param name="controller" value="true" /> 
            <param name="autoplay" value="False" /> 
            <param name="scale" value="aspect" /> 
            <param name="cache" value="true"/>
            <param name="saveembedtags" value="true"/>
            <param name="postdomevents" value="true"/> 
               
            <!--[if IE] --> 
            <EMBED name="movie"
                height="292"
                width="330"
                scale="aspect"
                src="https://securedomain/video.mp4"
                type="video/quicktime"
                pluginspage="www.apple.com/quicktime/download"
                controller="true"
                autoplay="False"
            /> 
            <!--[endif]--> 
        </object>

The fix was just to change this to https. https://www.apple.com/qtactivex/qtplugin.cab. 

<object id="videoObject" classid="clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B" 
            codebase="https://www.apple.com/qtactivex/qtplugin.cab" 
            width="330" height="292"> 
            <param name="src" value="https://securedomain/video.mp4" /> 
            <param name="controller" value="true" /> 
            <param name="autoplay" value="False" /> 
            <param name="scale" value="aspect" /> 
            <param name="cache" value="true"/>
            <param name="saveembedtags" value="true"/>
            <param name="postdomevents" value="true"/> 
               
            <!--[if IE] --> 
            <EMBED name="movie"
                height="292"
                width="330"
                scale="aspect"
                src="https://securedomain/video.mp4"
                type="video/quicktime"
                pluginspage="www.apple.com/quicktime/download"
                controller="true"
                autoplay="False"
            /> 
            <!--[endif]--> 
        </object>

Fortunately our users have the option of choosing the HTML5 Video player meaning they don’t need to install any 3rd party plugins to view videos.

CPF Contribution Rates for new Singapore Permanent Residents (SPR’s)

By
Recently my wife and I applied and got approved for Singapore Permanent Residency. After completing the formalities the most significant immediate change is the contribution to CPF which is Singapore’s mandatory social security savings scheme requiring contributions from employers and employees. CPF contributions start from the date you obtain SPR status, which is the date of the entry permit.   Being a relentless budgeter I needed to know exactly how much I and my employer would have to contribute so that I could adjust my budget accordingly as the employee contributions get deducted from the monthly salary. After doing some research I discovered that there is a “graduated” approach to CPF contributions for new SPR’s where the contributions gradually increase in the first and second year and then upon reaching the third year are at the full amount. Note: There is an option for employers to contribute the full amount for year 1 and year 2 and the employee can use the graduated rate, b…

Implementing Custom Castle Windsor Facilities

By
If you’ve been following my posts you would know that I love Castle Windsor. One of the many useful features I have found is the Facility and I’m going to try and give a good example how you can make use of this. In a recent post I showed how you can add Cross-Cutting concerns to your application by using Interceptors.Now when configuring the Container you can explicitly configure each Interceptor per Service but when you have lot’s of components it can get pretty hard to maintain after a while and can also introduce subtle issues if someone forgets to configure it correctly.Below is how you would configure your Container without using a Facility. On the last line we are specifying the Interceptor explicitly. public void Configure() { container = new WindsorContainer(); container.Register( Component.For<CacheInterceptor>(), Component.For<ICacheProvider>() .ImplementedBy<WebCache…
