To use same exit node for two different site i can use in torrc:
AllowDotExit 1 MapAddress site1.com site1.nodeA.exit MapAddress site2.com site2.nodeA.exit
But in this way i use always the same exit node for site1 and site2.
I want to use the same exit node for site1 and site2, but the exit node must change like other exit node. For example, if in tor browser i use "New Tor Circuit for this Site" when i am on site1 and then go to site2, the new exit node used on site1 must be the same on site2. Is this possible?
