[SR-Users] Serial Forking with differing next hop for each branch?

Hi I have a scenario where I need to implement serial forking but each destination has also a next hop proxy. I can do the forking using append_branch, but how can I set the destination URI for each branch? In some cases the R-URI does not change, only the next hop proxy. Example: R-URI                         Next Hop user1(a)domain.com  XXX.XXX.XXX.XXX user1(a)domain.com  YYY.YYY.YYY.YYY user2(a)domain.com  XXX.XXX.XXX.XXX I was thinking I could use a htable to store the next hop using the R-URI as the key, but as can be seen above there are possibly duplicate R-URIs with only the next hop changing. Thanks. -- -Barry
