Yakov Kopel updated TS-1058:
----------------------------
Description:
When the Trafficserver is trying to send response to the client, it terminate
the session after it.
Although I added the "KEEP-ALIVE" mime field - it didn't work.
The debug dump is looking like this:

The Solution:
I'm adding a patch of functino that rasing the internal flag of KEEP-ALIVE, so
the trafficserver will realy believe us that we want to keep this connection
alive :)
Example for the usage of the new function:
// Tell the trafficserver to not close this connection (keep-alive)
TSHttpTxnCloseAfterResponse(txnp, 0);
was:
When the Trafficserver is trying to send response to the client, it terminate
the session after it.
Although I added the "KEEP-ALIVE" mime field - it didn't work.
