[OpenLayers-Users] Browser back and forward button

[Christian López Espínola]

Hi Matthew,

It isn't integrated with the browser, but a good start if you want to
implent this is the NavigationHistory control.
http://dev.openlayers.org/releases/OpenLayers-2.6/doc/apidocs/files/OpenLayers/Control/NavigationHistory-js.html

Example here:

http://openlayers.org/dev/examples/navigation-history.html

I don't know if anyone has done what you want before.
