Echo service implementation - copying the request entity as the response
Hi All
I wanted to write an echo service, and found that I cannot copy the
entity from the request as the response.. Also see :
http://hc.apache.org/httpcomponents-client/httpclient/xref-test/org/apache/http/localserver/EchoHandler.html#95
For small requests copying it into a byte array would work, but I am
suspecting there is another way?
thanks
asankha

This explains the reason clearly..

Hi Asankha
The problem is that lots of HTTP agents out there (including HttpClient
3.x and HttpClient 4.0) can only handle request / response content
streams sequentially. That is, they can start reading response content
only after the request content has been fully written out.
You can try passing the input stream of the incoming request entity to
the outgoing response entity to avoid buffering the entire message
content in memory, but I suspect this will not work with many HTTP
agents out there, especially for larger content entities.
