it *was* that issue: with the development version of
OpenLayers layers are always retrieved just once. Thanks
Andreas. Just curiosity, can you give me a pointer to what the
problem was?<br>

<font face="Times New Roman, Times, serif">Hi,
just to clarify, the issue you are seeing (if it's the issue I
think
it is) was fixed *after* 2.11.

Hi Andreas,<br>
</span></font>
<p><font face="Times New Roman, Times, serif"><span class="sender">No,
I use OpenLayers 2.11. I see now that it has something to do
with my proxy. </span><span class="sender">All maps are on

retrieved twice. <br>
</span></font></p>
<p><font face="Times New Roman, Times, serif"><span class="sender">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.<br>

<font face="Times New Roman, Times, serif">Hi all,<br>
<br>
I made a very simple OpenLayers test site, displaying a simple
local MapServer map as an untiled WMS service. Works fine, but
when I look in the server log, each OpenLayer GetMap request
results in *two* identical requests to the server. Can anyone
confirm this, and why does it happen?<br>
