Hi list, in numerous example configuration files, I saw the following statement (where "route(1)" is the final routing block): % if (loose_route()) { % route(1); % } % % ... % % route(1); It works for me, but I am just wondering what causes the loose_route() function to return a failure ? In this case, it seems number of actions used to be performed before calling the final message routing block. Naturally, I checked the rr module documentation, but the descriptions is very small and only refers to RFC 3161. I have read some parts of this RFC, thus I know what loose routing means (basically, it uses always the same URI all along the proxy string, removing IP addresses in the Route header gradually, contrariwise to strict routing which puts the real URI at the end of the Route header and use the next proxy as URI). In spite of this, I cannot figure why this function should fail. I'm pretty confident this is to help for the scripting logic, and I was supplied with some explanations. Thank you.
