Facebook download xd_proxy.php while scrolling

Question

Hi, does anyone know what happens with iframe apps on facebook to download xd_proxy.php? I did not notice that this is a new or existing problem, because the screen of my applications is fixed, today, when I change the code, scroll the screen with the mouse and find that xd_proxy is loading while scrolling (regardless of kb arrow, scroll bar. .), I am looking for some messages in google and stack overflow, but no luck, none of them can solve it, I will try to add channelurl, rebuild javascript ... etc., but no luck, please help, thanks in advance.

Now it is registered as a bug in tracking Facebook errors. The best way to fix this is to vote for him!

Answer 2

Facebook fixed the error that we were expecting in our SDK SDK this week, so we planned to move from the old JS SDK to the new one, but during the final testing it also affected. It looks like the location of the window is being reported.

Does anyone know if this is new and what exactly is it used for? Can it be disconnected? I wonder what this will do with performance in different environments.

Answer 3

This starts after FB.init in window.fbAsyncInit is called using the SDK SDK. It passes the height and width of the client and scrolls as parameters with type canvasPage.update. Maybe, but I don’t know, something is connected with an error at the beginning of this year when the applications in the iframe did not resize, something like work.

I also noticed this today, and initially thought it was due to the fact that FB.Canvas.setAutoResize () is called secretly, but it seems that scrolling is tied to this update.
