How do disable Transfer-Encoding in Tomcat 6

Question

I have a web application running on Tomcat 6.0.29 server and JDK 1.6. When I send the response to the client, Tomcat sends ``` Transfer-Encoding: chunked ``` in the headers when the response size is > 8KB. For responses < 8KB, it sends ``` Content-Length : ``` I understand that Chunked encoding is the preferred way to handle bulk responses, however our clients do not want to change their code (as it is distributed all across the servers). How can I disable Chunked encoding in Tomcat? I could Disable HTTP/1.1 in Tomcat and enable HTTP/1.0 (not sure how I can do this) I tried the following with no success: In Connector tag in `server.xml`, I set `bufferSize =" 65536"` ``` Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" bufferSize="65536" socketBuffer="65536" redirectPort="8443" /> ``` Using NIOConnector in server.xml with following configuration: ```

Accepted Answer

The only way I could get it working is by setting the BufferSize on response.

`response.setBufferSize()` sets the `Content-Length` header of the response size. Once the response size goes beyond the bufferSize it would fallback to `Transfer-Encoding: Chunked`. The buffer size should be set to an appropriate value. Setting it to a higher value would buffer all of the response in memory before flushing it. So the value should be set to an optimistic size.

Few of my clients are depending on `Content-Length` response header. I have to set this for backward compatibility. By default Tomcat buffer size is set to 8K (I think for Weblogic/Websphere this is 32K bytes).
