If you are viewing an in-app browser, then you can instead of loading the page, retrieve the html for the page you want to view. Then, if possible, strip out the offending redirection (it might be javascript based) and display the modified HTML. At the end of the day, if you have access to the page that you are displaying, you should be able to find a way to strip out the offending stuff.
Now, if linked in changes their web page, you would probably need to update this code, but this way would work.
