Redirection enabled and TIME_WAIT

["Dunkin, Nick" <Ni...@ccur.com>]

Hi

We are using the proxy.config.http.redirection_enabled feature in ATS 7.0.

We are finding that when ATS receives the 307 Redirect from Origin, it closes that connection and creates a new one to retrieve the redirected content.  The result is that, when under load, we end up with a large amount of sockets in TIME_WAIT.

I can’t find any other configuration options that might alleviate this situation.

Does anyone have any insight or advice to offer?

Many thanks,

Nick Dunkin

Hi Sudheer

Thanks for the reply.

Yes, and there is no Connection: close either.  All other Origin request behavior is normal.  We only see this when the Origin issues a redirect.

Thanks,

Nick

Do you use persistent connections to the Origin? If so, the connection should not be closed by ATS (unless the Origin returned 307 with a Connection : Close header).

Thanks,
