i tried to replace k domain module with s, but got this kind of show stopper: 0(3499) : <core> [cfg.y:3020]: parse error in config file, line 1877, column 30: Command cannot be used in the block the line in question is if (is_local(&quot;(a)ruri.host&quot;)) { and the block is branch_route block. can BRANCH_ROUTE be just added to the list {"is_local", is_local, 1, fixup_var_str_1, REQUEST_ROUTE|FAILURE_ROUTE }, or will it result into problems? -- juha
