Not something you have to worry about. A properly configured and  
implemented HTTP server will only send compressed data when the  
browser says it can handle it. The browser controls whether  
compression can be used. It does this by sending an Accept-Encoding  
HTTP header indicating which compression methods it supports. The  
server can then choose to use one of those compression methods or can  
ignore compression entirely.

Early browsers, or those using HTTP/1.0, will not send this header  
therefore compression should not be performed.

Usual form is:
	Accept-Encoding: gzip, deflate

The HTTP server indicates compression is in effect by sending the  
Content-Encoding header. This should never be sent unless the browser  
has already indicated it can accept such encoding.
