I’m running nginx 1.3.9 with memcached\_pass and I have set memcached\_gzip\_flag in an attempt to serve gzipped content directly from memcached (mainly to save memory on my memcached processes, which get pretty large). My gzip flag is being detected properly–nginx adds the Content-Encoding header–but I get 330 errors saying the content encoding is incorrect. Every test I’ve made indicates that the data I am storing is valid gzipped data. Does anyone have any advice on how to troubleshoot this? Thanks so much!

PS: I’m writing the data using Dalli ([GitHub - petergoldstein/dalli: High performance memcached client for Ruby](https://github.com/mperham/dalli)) with compression on and raw set to true. Dalli sets the bitmask for compression to 0x2 (all of this appears to be working correctly).

As far as I can tell from [1], it stores zlib stream, not gzip (which is a different format on top of the same compression algorithm, see zlib.h for details). It likely can be easily adapted to use gzip though.

Right you are. Thanks for the second set of eyes! I’ve submitted a PR to Dalli to add a gzip compressor and I’m using a custom one now. It’s working wonderfully.
