I have two wireless ADSL routers sitting right next to each other, each with his own internet connection.

I'd like to be able to connect Computer A (connected to Router A), to Computer B (connected to Router B), while keeping both router's internet connection individual. So Computers A and B can talk, but still use their individual routers for reaching the internet.

Is this possible?

Yes. Connect a third device to both routers, configured to route traffic in the manner you prefer (load balancing, round robin or such that computerA uses routerA and computerB uses routerB).

There are a large number of options depending on what scale of solution you're looking at (eg, is this a 2 person solution for a pair of 2 Mb/s DSL lines, or a 200 person solution for a pair of 50 Mb/s DSL lines).

Sounds like you're after a policy based routing or similar, though there's a non-trivial challenge in differentiating between web browsing and downloading over HTTP. I know that pfSense has multi-WAN capability and it may do what you're after.

Another device that can route the internal network traffic with each computer group in a separate segment, would do what you want. When traffic targeted to public addresses comes from Segment A (192.168.100.X) use ADSL router A, when it comes from Segment B 192.168.200.X. use ADSL Router B. Also configure a static route to direct traffic from Segment A to Segment B and viceversa.
