Verifying website components are compressed

[AgentZap]

Is there a Firefox add on or any other stand alone app that will allow you to see if individual components are sent from the webserver to you compressed or not? For what I'm trying to verify I can't use one of those online scans.

What firebug option shows that?

Wireshark or other "packet sniffer" apps can tell you, but if fiebug can say it's probably easier to read.

Download the "Web Developer" Addon for FireFox, then Go to: Information > View Document Size

This tells you what various elements are compressed or not... Though without details of what you are looking for I don't know if it's what you need or not.

Enable Net monitoring, click on the item you want to verify, and the HTTP header information should tell you if it's compressed or not.

I noticed on files that are supposed to be compressed the Response Header shows the Content-Encoding line as gzip which is perfect, but on other files the Content-Encoding line is missing. If the content-encoding line is missing in the response header does that mean the file was not compressed? I was kind of expecting Content-Encoding: none or something like that instead of the line being omitted--is something else going on in that case?

It was hard to tell in Web Developer if the files were actually compressed or if it was telling you what size it would be compressed or uncompressed.
