seam-remoting response not compressed

[hotribao]

I am using seam-remoting to make ajax calls. I enabled gzip compression on tomcat server by setting compression="on" on the "Connector" tag (in server.xml) as following:

    <Connector compression="on" connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>

However, when I view the response header using FireBug, the response seem not to be compressed. Below is what I see with Firebug:

Server     Apache-Coyote/1.1
Content-Type     text/xml
Content-Length     1589
Date     Thu, 30 Jun 2011 10:26:13 GMT

In other "traditional" seam ajax response (not seam-remoting), the responses are compressed. Bellow is what I see with Firebug for those reponses:

Server     Apache-Coyote/1.1
X-Powered-By     JSF/1.2
Ajax-Response     true
Cache-Control     no-cache, must-revalidate, max_age=0, no-store
Expires     0
Pragma     no-cache
Content-Type     text/xml;charset=UTF-8
Transfer-Encoding     chunked
Content-Encoding     gzip
Vary     Accept-Encoding
Date     Thu, 30 Jun 2011 10:42:52 GMT

Did I miss something in the configurations?

seam version 2.2.1.CR1
tomcat 6

I found myself the answer for my question. It turns out that there is a mininum size (which I don't know how many) which trigger the compression on tomcat. Below that size, the response is not compressed. I try to make my seam-remoting response bigger, then I can see it gziped
