[SR-Users] t_suspend / t_continue & insert_hf

[Fuad Trle]

Hi Henning,

I have tried this, but without success. *This function can be used from
REQUEST_ROUTE or core REPLY_ROUTE.* t_newtrans & http_async_query force me
to enter a new routing block and call fail with "500 I'm terribly sorry,
server error occurred (1/TM)". There is no explicit exit at the end of
route(HTTP) but for some reason execution stopped and did not continue in
request_route.

I don't think I can fulfil those requirements (call function in request
route and before record_route). Suspend is the last option (after location
lookup and parallel forking).
