posturl - Can the delay be omitted?

[James Cook]

When processing credit card payments, I send info to the credit card 
processor about the payment. At some point the processor sends back 
the approval and requires a postback from my server to complete the 
transaction.

When the approval comes in, I use posturl to repeat the transaction 
back to them, then they send a final confirmation. Sometimes their 
server may take  many seconds or even a minute to respond the 
postback. My server sits and waits for a while, then times out if 
there's been any delay.

I dislike having the server stalled and waiting at all,  but if it 
has timed out, when the response does come, it's recorded as an error 
and the transaction remains incomplete.

Is there any way to do something like posturl, but without any 
waiting at all?  I could simply have my server treat the response as 
a new hit and deal with it.
