I'm inserting some headers after getting value from http_async_query. If a call is relayed, I see them. But If I t_suspend and t_continue call (before time out), I do not see added headers. Here is flow:

route(START)

t_newtran();

#.. prep for query

http_async_query("url","HTTP");

route(HTTP)

#.. collect and using data from query

insert_hf("$var(key): $var(value)\r\n");

t_store();

if (registered("location") {

    route(RELAY);

} else {

    t_suspend();

    exit;

}

route(AWAKE)

t_continue();

I see that the branch index ($T_branch_idx) is 0 at start. 1 after http query, +1 if there is forking or location. +1 after t_suspend. It looks like t_continue uses a branch with index after t_suspend. I tried with t_save_lumps() to carry over changes.

Any idea how to do this?
