Hi John,
1) if the request does not match any dialog it will go on the "else"
branch where it simply logs the "valid request" - this is a simple
example, but the idea is that without dialog state you cannot check if
valid or not; and you maybe do not create dialogs for all your calls and
maybe not all your sequential request are part of a INVITE dialog (you
may have re-SUBSCRIBE or NOTIFYs)
2) the function just fixes, you need to send it out as usual via the
t_relay(),

I was looking at usage of validate_dialog() and saw the following
snippet from module documentation page. If you check the else part...
as per my understanding if a dialog is not found ($DLG_status) will be
NULL) it will go to else part which indicates a message has To tag but
dialog not found. How can it be a valid in-dialog request.
if (has_totag()) {
loose_route();
if ($DLG_status!=NULL && !validate_dialog() ) {
xlog(" in-dialog bogus request \n");
} else {
xlog(" in-dialog valid request - $DLG_dir !\n");
}
}
Also there is one more code
if (has_totag()) {
loose_route();
if ($DLG_status!=NULL)
if (!validate_dialog())
fix_route_dialog();
}
After calling fix_route_dialog() do I need to just relay the message?
I mean this function will "fix" the message and send?....I was trying
to look for some security check where someone can inject a route
header and a to tag (Bogus of course) to reach to my gateways through
my proxy.
