John While it is not going to be pretty it is certainly doable. Assuming you intend to use blocking I/O model (1) Create a custom version of the ChunkedOutputStream. Most likely will need to copy the entire class and tweak it quite a bit to make it work the way you want (2) Subclass EntitySerializer and make it use your custom ChunkedOutputStream when serializing chunked entities or a specific type of entities. (2) If you intend to use HttpCore only, subclass DefaultHttpClientConnection and make it use your custom EntitySerializer. If you would like to use HttpClient with all bells and whistles, follow these instructions of the HttpClient tutorial: http://hc.apache.org/httpcomponents-client-ga/tutorial/html/advanced.html#d4e1333 Hope this helps Oleg --------------------------------------------------------------------- To unsubscribe, e-mail: httpclient-users-unsubscr...@hc.apache.org For additional commands, e-mail: httpclient-users-h...@hc.apache.org
