No roundtrip on resize action of browser window in Web Dynpro ABAP

Hi everybody,

i got a problem with my webdynpro abap. In the right part of my webdynpro application i do show a PDF that i got via PI from a diffrent server. Now i did implement the resize action of the interface IF_WD_CLIENT_INFORMATION. With the client information i do set the hight of my transparent container on the left side. That's fine so far.

The resize action now sets the actual hight of the client browser window to the hight of the transparent container. But every resize action releases a roundtrip and get's the PDF one more time from the PI. I would like to stop the application of doing that. So is there a way to not do a roundtrip when resize the window ?

Or has anybody an other solution on my scenario ?

Thanks for your suggestions.

Thx.

Thomas
