[SR-Users] via header not removed wit hremove_hf()

during testing I need to remove a Via header This is the code snippet route[REPLACE_VIA] {     xlog ("L_INFO", "[REPLACE_VIA] Start of block\n");     xlog ("L_INFO", "[REPLACE_VIA] $hdrc(Via) Via headers\n");         if(remove_hf("Via")) {                 xlog ("L_INFO", "[REPLACE_VIA] removed Via\n");         }         else {                 xlog ("L_INFO", "[REPLACE_VIA] did not remove Via\n");         }     xlog ("L_INFO", "[REPLACE_VIA] $hdrc(Via) Via headers\n"); and this is the logs output Sep  7 08:00:00 INFO: _LOG: 3a547f956d65fe985ba189916047fc320ae150ad: [REPLACE_RURI] Start of block Sep  7 08:00:00 INFO: _LOG: 3a547f956d65fe985ba189916047fc320ae150ad: [REPLACE_VIA] Start of block Sep  7 08:00:00 INFO: _LOG: 3a547f956d65fe985ba189916047fc320ae150ad: [REPLACE_VIA] 1 Via headers Sep  7 08:00:00 INFO: _LOG: 3a547f956d65fe985ba189916047fc320ae150ad: [REPLACE_VIA] removed Via Sep  7 08:00:00 INFO: _LOG: 3a547f956d65fe985ba189916047fc320ae150ad: [REPLACE_VIA] 1 Via headers From the logs it looks like the remove_hf returns true and we have the header removed, but its still counting the Via header and the Via Header is still present when the INVIE is releyed on  Regards, Richard
