python - Fill memcached with compressed data, serve directly from nginx -

in python generate complex static pages. put them memcached next time they're requested, can served directly nginx (without hitting python @ all)

this worked great until realized how inefficient store uncompressed html in nginx. tried manually gzip data before storing it, , nginx return directly (just setting content-encoding:gzip), although nginx's documentation suggests it's possible, haven't been able work.

in test, had python fill cache data gzip in python via npe's answer @ how gzip compress string in python? . set memcached flag these 1.

with no other changes, @ point, nginx serves raw data, gets displayed junk in browser.

after that, changed nginx settings location, setting memcached_gzip_flag field 1 nginx know data gzipped, nginx still served raw data. i've experimented every combination of nginx's settings: gzip on , memcached_gzip_flag 1 in cases browser displays raw data (after first direct python hit); in cases firebug reports content-encoding gzip (but still showing raw gzip data) , in others, content-encoding not set.

overall, plan of attack trick nginx serving already-compressed data right headers browsers unzip it.

i'm in nginx 1.6 & memcached 1.4.13

here's related nginx config lines, work. first hit gets data python fills cache, 2nd hit serves directly memcached.

location ~* <matching stuff>  {     if ($request_method = post){         break;     }     memcached_gzip_flag 1;     set $memcached_key $uri;     memcached_pass 127.0.0.1:11211;     error_page 404 405 502 = @redo;     default_type text/html; } 

update: experimented more (details in comments), still no result.

update post bounty: have no answer @ this. basically, can't memcached_gzip_flag function work @ all. note future answerers: if answer make bounty & award you. preferable having half of bounty automatically awarded wrong answers.

the documentation little sparse, if i'm understanding correctly: memcached_gzip_flag specifies bits in flag associated cached object indicate content gzipped. need like: memcached_gzip_flag 1, store data flag having matching bits set:

 memcache.set('key', 'gzipped-value', flags=1)
