UIWebViewNavigationTypeLinkClicked event not getting fired for certain links

Question

I am using a UIWebView as an embedded browser within my iphone app. I am using the shouldStartLoadWithRequest function to handle UIWebViewNavigationTypeLinkClicked events for links clicked by a user. It is working as expected for a number of sites, but not for all.

For example: when I click on any of the links on website http://www.foxnews.mobi, the UIWebViewNavigationTypeLinkClicked event is not getting fired. Same thing happens for some other sites.

I read somewhere that links with blank target do not fire the event, however this is not the cause of the problem in my case.
