Enable GZip Compression Enable HTTP GZip compression. -true -false Should it be set to true or false in Shopping cart admin tool? Anyone know about OScommerce shopping cart tool?
Gzip is a way of compressing webpages, so that thery are sent to the client compressed, using lesser bandwidth. It usually better to set it to true (that is, enable it).
You can look at en.wikipedia.org/wiki/Gzip for more information too. But as cbn81 mentioned it is used to compress data that are send to the user because of bandwidth savings.
here is a cool little tool that will tell you if your site is GZip'd and if so, how much http://www.gidnetwork.com/tools/gzip-test.php cheers -Bs
make sure your server isnt automatically using it before you decide to turn it on, Im not sure if it will negatively impact anything
