[Plugin: WP Super Cache] GZIP Compression not working with WP-Super-Cache

The plugin has had gzip support since it was first released. Your host probably has gzip enabled in php.ini or something as the plugin hides those options when the server already does it.

following link says my blog is not having GZIP enabled ?? please help me.

Your host may have disabled compression with the “WPSC_DISABLE_COMPRESSION” constant. You should probably talk to them if you don’t see the option, “Compress pages so they’re served more quickly to visitors” on the Advanced settings page.
