[OpenLayers-Users] singleTile mode for Grid layers and map viewport resize

[Armin Burger]

Hello

I have a question regarding the singleTile mode for Grid type layers:

I have set the "map" <div> to 100% for width/height. When the parent div 
is resized due to browser window resize (with the mouse), the "map" div 
is automatically resized as well. This however causes lots of new images 
requested from the server during this resize. This I would like to avoid 
since it causes huge loads on the server (a quick and small browser 
window resize easily triggers 20 new image requests). And in browsers 
like Chrome it takes a quite long time until the new map image is again 
displayed.

I would prefer that the request for a new map image is just fired when 
the window resize is finished, but not already permanently during 
resize. Also I'd prefer that during the resize the existing map image 
for the singleTile layer remains visible.

Are there any ways to achieve this? Either with configuration settings 
or code modifications?

I tried the setting 'tileLoadingDelay' but it had no effect on this issue.

Thanks in advance for any hints

Armin
