[jira] Commented: (CXF-1387) Support for GZIP compression of HTTP
payloads
[ https://issues.apache.org/jira/browse/CXF-1387?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12613432#action_12613432 ]
Melloware commented on CXF-1387:
--------------------------------
Outstanding interceptor. It is very well written and has provided an invaluable service to my current Web Service project. This should definitely be part of the main CXF distribution!

> This patch contains a pair of interceptors I wrote to provide support for proper GZIP compression of request and response messages. I originally started from the configuration_interceptor sample but the code has evolved quite a long way from there now.
> There are two separate interceptors. GZIPInInterceptor looks in the PROTOCOL_HEADERS for a Content-Encoding of "gzip", and if found it wraps the message's InputStream with a GZIPInputStream to uncompress the payload. It restores the original input stream at the end of processing (failure to do that originally left me with lots of stale HTTP connections).
> GZIPOutInterceptor applies gzip compression to outgoing messages whose payload is larger than a configurable threshold (default 1kB), and sets their Content-Encoding in the PROTOCOL_HEADERS to "gzip". Smaller messages are not compressed as it's probably not worth the overhead.
> As currently written, these interceptors are only for use on the client side (compress the request, uncompress the response). In my services I implement the server-side compression outside of CXF via a servlet filter (http://sourceforge.net/projects/pjl-comp-filter), but if you think it would be useful I can modify the interceptors to support this too - the "in" interceptor should work as-is, the "out" one would have to be made conditional on the Accept-Encoding header supplied in the client request.
