I'm aware of control-flow module's capabilities. Another great module by the way :) A question, though: " The control flow method does not normally reject requests"... what does "normally" means? The procedures described above were implemented 1.5 years ago and unluckily the control-flow module didn't exist at the time. > On the flipside, if you're hitting a tile cache there's another way > to get around that issue, which is to using multiple domain names for > your servers and tell OL to round robin the requests on those. > See for example: > http://wiki.openstreetmap.org/wiki/OpenLayers/FasterTiles Yep, we use it too.
