Webservices host often timeout - Client not receiving response

Hi,

We have a web services running to facilitate our clients in performing
transactions. Below is the sample message flow:

1)
App -> WS
WS - perform transact
WS - send response
2)
WS -> App
App - ack receiving
App - confirms transact finish

Problem arises when in part 2, the client does not receive the confirmation
of a successful transaction even though the webservice host has already sent
out the message. Thus continues to resend a fresh command to perform the
transaction again.

In this scenario, the host has already performed the transaction.
This results in duplicated transactions being performed:

1)
App -> WS
WS - perform transact
WS - send response
2)
App ???
App - no response from host
App - resend command
3)
====
duplicate
====
App -> WS
WS - perform transact
WS - send response

Any suggestion to workaround this?

Thanks,
CK
