Hi all,
I have a little Lua example that trips all the ssn and txn hooks. The callback
function for each hook just calls TSHttpTxnReenable(). I'm finding that
re-enablin the transaction in response to a TS_EVENT_HTTP_READ_RESPONSE_HDR
event always asserts.
I figured that calling TSHttpTxnReenable() was always the right thing to do ...
are there cases where it must not be called, os is this just a bug?
