question wrt to the response from Allen (posted below):
1) if i use a request-response http receive adapter, then response sends back a 200 success code, and on the other hand, for a one-way http receive adapter, the adapter sends back a 202 success code. is this correct?

2) using the request-response http receive adapter, is it possible to send other content in the response in addition to the 200 success code?

Original question and response from Allen follow:
-----------------------------------------------------------------------------------------------

>Correlation token is XML string in form of
><BizTalkHttpReceive><CorrelationToken>xxx-GUID-xxx</Correlation
>Token></BizTalkHttpReceive>. The GUID can link your future request to the
>original message.
>
>Sample usage: If you scenario is a long-running process that immediate
>response is not possible, Then you can set it up to return a correlation
>token GUID. In you scenario that the user with this GUID, they can query
>the result or progress at a later time.

>202 is One-way either with no body or XML string containing correlation
>token
>200 is Request-Response where a response message is being returned.

server, the HTTP receive adapter sends an HTTP code 202 back to the client
indicating that the request was accepted.
> Optionally, the HTTP receive adapter can send a message correlation token
on the HTTP response. This correlation token represents the message within
BizTalk Server. If the HTTP receive location is in a request-response port,
the adapter returns success code 200 along with the response message. "

it means/represents, so if anyone could shed some light on this, that would

and when does it send back code 200?
