Summary: 'reply' function involving 'sl_reply' and 't_reply'

Initial Comment:
Hi, IMHO is not very friendly being dealing with 'sl_reply' or 't_reply' depending on if the transaction has been already created.

Sometimes it's not clear which one to use (for example if we are processing on_reply_route and so).

I know that both "t_reply" and "sl_reply" belong to different modules (tm and sl) but it could be nice a new function just called "reply" that would call the appropiate function t_reply or sl_reply depending on the existance of the transaction.

This is:

  if xxxxx {
    reply("403", "Forbidden");
  }

  on_failure_route[1] {
  if xxxxx {
    reply("500", "Bad gateway");
  }


Is it feasible?

Message:
Well, the fact is that "t_reply" can be used just when the transaction has
been already created, this is, after calling "t_newtrans()", in
"on_failure_route" (so "t_Realy" was called before and created the
transaction). And "sl_reply" can be used just when the transaction doesn't
exist for the current request.
In fact you get a logical error if you try to use "sl_reply" when the
transsaction already exist or "t_reply" when the transaction doesn't
exist.

So, in conclusion, there is no possibility of choosing wich one to use. 
If the transaction already exists you must use "t_reply", and if not, you
must use "sl_reply". So why not a common function called "reply()" that
would call the appropiate function depending on if the transaction exists?

Message:
i'm not convinced yet that this is needed.  in my script i forward all
requests statefully so i know that when reply comes, i need to process it
statefully.  are you saying that you forward some requests stafully and
some statelessly?  perhaps you can give another example.
