We have a multi-node REST architecture, using CXF:
Client calls Server 1
Server 1 looks up the host/url and calls a similar service on Server 2
Server 1 gets the Response from Server 2 and returns it to the client (no
unmarshalling) For example, this is the call from Server 1 to 2:
public Response testBackup(final Long hostId, final String config) {
// create server2Proxy based on hostId
return server2Proxy.testBackup(config)
}
This works and allows us to avoid the unnecessary work of
unmarshalling/remarshalling the response from Server 2. First question, is
this an appropriate CXF implementation?
One problem with this is we see a duplicate Date header from the Server 1
response:
HTTP/1.1 200 OK
Date: Thu, 04 Aug 2011 23:02:04 GMT
Date: Thu, 04 Aug 2011 23:02:04 GMT
Content-Type: application/xml;charset=UTF-8
Server: Apache-Coyote/1.1
Content-Length: 8587
When I run it on Tomcat, Tomcat chunks the response and duplicates the
Transfer-Encoding and Server headers:
HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
Date: Thu, 04 Aug 2011 22:44:36 GMT
Transfer-Encoding: chunked
Server: Apache-Coyote/1.1
Content-Type: application/xml;charset=UTF-8
Transfer-Encoding: chunked
This normally could be ignored, however in one of our environments, The
chunked response gets corrupted, not including the chunk size before each
chunk, as required, and the client fails. Any ideas on this? We are on CXF
2.2.11. Thanks,
Andrew
