This includes the port in :arg:`addr`. The address family is also set by the contents of :arg:`addr`. The address data is copied out of :arg:`addr` so there is no dependency on the lifetime of that object. This hook must be called no later than TS_HTTP_OS_DNS_HOOK. If this is called prior to TS_HTTP_OS_DNS_HOOK, DNS resolution will not be done as the address of the server is already known. Return Value ============ :data:`TS_ERROR` is returned if :arg:`addr` does not contain a valid IPv4 or IPv6 address with a valid (non-zero) port. Notes ===== If |TS| is configured to retry connections to origin servers and :func:`TSHttpTxnServerAddrGet` has been called, |TS| will return to TS_HTTP_OS_DNS_HOOK so to let the plugin set a different server address. Plugins should be prepared for TS_HTTP_OS_DNS_HOOK and any subsequent hooks to be called multiple times. Once a plugin calls :func:`TSHttpTxnServerAddrGet` any prior DNS resolution results are lost. The plugin should use :func:`TSHttpTxnServerAddrGet` to preserve any DNS Results that might need. See Also ======== :manpage:`TSAPI(3ts)`, :manpage:`TSHttpTxnServerAddrGet(3ts)`
