Hi, While I was the network traffic in my browser for an issue I was working on. I noticed the response sizes being unusually large. When I compared it against a similar sized 3.6 installation the response was huge. Checking the headers it appears that the response no longer is gzipped before being send to the user. Does anyone know of any changes to that recently? I am unsure of what exactly gzipped the responses to begin with. I was assuming either a filter or some jboss setting. If anyone could shed some light on this it would be appreciated. Thanks, Alexander

Looking at the request headers the request is made with text/x-gwt-rpc. Thus not matching the regex, and thus the response is not compressed. So it appears the content-type header changed instead of the valve/filter. I will see if I can find out why that changed. Depending on the result we might have to adjust the filter to include text/x-gwt-rpc.
