On backend connection reuse, a hash is calculated from various parameters, to ensure the selected connection match the requested parameters. Notably, destination address is one of these parameters. However, it is only taken into account if using a transparent server (server address 0.0.0.0). This may cause issue where an incorrect connection is reused, which is not targetted to the correct destination address. This may be the case if a set-dst/set-dst-port is used with a transparent proxy (proxy option transparent). The fix is simple enough. Destination address is now always used as input to the connection reuse hash. This must be backported up to 2.6. Note that for reverse HTTP to work, it relies on the following patch, which ensures destination address remains NULL in this case. commit e94baf6ca71cb2319610baa74dbf17b9bc602b18 BUG/MINOR: rhttp: fix incorrect dst/dst_port values
