[ns] DSR caching

[Amer Filipovic]

Hi,

I am trying to modify the DSR code in the way that it caches the routes.
I am using version 2.1b9a

As far as I can tell, in the "recv" block, as soon as the packet is
identified to be for "this" node, the method handlePacketReceipt() is
invoked which does NOT cache the path in the source route header.

Other functions such as handleForwarding() do.

I am at a bit of a loss to explain why this is so, or I am missing the
place where this information is cached.

Can someone either tell me
- where this information is cached, or
- why it is not cached once the packet is received by the intended
destination.

Thanks,

Amer
