Hi Andreas,

No, I use OpenLayers 2.11. I see now that it has something to do with my 
proxy. All maps are on webservers in an internal network and are 
accessed via one proxy.When I run the page on the local server, maps are 
retrieved only once. When I access that same server from the outside, 
via the proxy, all maps are retrieved twice.

Although this is probably not an OpenLayers problem, I would be 
gratefule for suggestions. It took me quite some time to get the proxy 
configuration running. It works now, but takes twice as much time as needed.

This might be due to a bug that has been fixed quite some time ago 
already. Which version of OpenLayers are you using? Andreas.
