Hi Daniel,
If it is the case then the ordering shouldn’t be 1,2,3,3 ? but I’m getting 3,1,2,3.
I tried to set $(branch(uri)[-1]) = $null; after the while block , but nothing changed L
Are you still getting all branches? Isn't the last one removed? Can you print branches before and after assiging $null? you can use:
$var(i)=0; while($var(i)<$branch(count)) { xlog("branch uri[$var(i)]: $(branch(uri)[$var(i)])\n"); $var(i) = $var(i) + 1; }
Cheers, Daniel
Thanks,
Ali

Hello,
next_gw() is also setting the r-uri, so for the last successful next_gw() you should not call anymore append_branch(). Try to remove the last branch after the while block:
$(branch(uri)[-1]) = $null;

Hi Daniel, I’m using this method because I’m having issue with append_branch where last gateway is listed first. For example if gateways are ordered in LCR_rule_target as 1,2,3 , I’m having them in contact header as : 3,1,2,3 I’m using below code : if (!load_gws(1, $rU, $fu)) { sl_send_reply("502", "Unable To lOad GatEwAyS"); exit;} while(next_gw()){ append_branch(); } sl_send_reply("302","Moved Temporary"); exit; } Any hint regarding the above would be appreciated.

The active branches of the request are added as contact header to the reply. So you can practically use append_branch() as many times as you need and then do sl_send_reply("3xx", ...). You don't need to append headers to replies explicitely.
