Zlib or Gzip

    zlib compressed data are typically written with a gzip or a zlib wrapper. The wrapper encapsulates the raw DEFLATE data by adding a header and trailer. This provides stream identification and error detection that are not provided by the raw DEFLATE data.

    The gzip header is larger than the zlib header, as it stores a file name and other file system information. This is the header format used in the ubiquitous gzip file format.

    They’re the same and do the same thing. Both compress your data. You use the one that you can use. For example, my web server already performs gzip compression so I do not turn on that option in WP Super Cache.

    If you have a WP Super Cache problem then you may want to consider posting to that plugin’s dedicated support sub-forum instead.

    Just to offer a quick suggestion here, WP Super Cache only offers gzip compression, so you’ll probably want to stick with gzip.

    However, the WPSC people my have a work-around for zlib, so you’ll probably want to post there anyway, as Jan directed.
