iframe - white page between two pages transition

Hi Team,
I have a mobile site.when i try to open this in a iframe, I see that between two different HTML pages, i see a white page and then the second page comes up.
example whne i click a href from Page A -->Page B ,before page B loads i seea blank White screen the Page B loads.
 
but when i try to open the same in normal browsers , I dont see a white page in between page transitions and work fine.
 
Can you please help.
