If you view the response headers of the page, you'll see something like:

Content-Type: text/html; charset=UTF-8
Content-Encoding: gzip
Transfer-Encoding: chunked
Cache-Control: no-cache,no-store
Date: Fri, 02 Feb 2007 14:28:05 GMT

The second line tells you (and the web browser) that the page is gzipped.

If you install the Web Developer extension for Firefox, there's a selection 
called View Document Size.  Here's a sample from that output:

Documents (1 file)	3 kb (17 kb uncompressed)
Images (6 files)	1 kb
Objects (0 files)	
Scripts (1 file)	1 kb (18 kb uncompressed)
Style Sheets (9 files)	31 kb
Total	36 kb (67 kb uncompressed)

Pretty handy, yes?
