Moloch Gzip Decode

As previously mentioned, the open source packet capture tool Moloch does a number of on-the-fly decoding functions, including decompressing gzip'd data from the Web server. In the screen shot below we see a response from the server to a GET request. Because there's a large amount of code in the response it's gzipped, so we need to decompress it to analyze what's in the response.

After turning on the "Decode Gzip" option, represented by the check box in the grey options bar at top, the gzipped data is instantly decompressed for us and displayed.
