Hi all

I got my modifying reverse proxy working by adding

proxy_set_header Accept-Encoding '';

before my body_filter_by_lua code block. This way I force the proxy to give me uncompressed data, and then the lua code works perfectly. I'll add a gzip on; at the end, to pass the data to the browser compressed.

Subject: does body_filter_by_lua get called when proxied server returns gzipped data?


I posted the recent thread on problems with body_filter_by_lua, and I think it finally has to do with the fact that my browser allows gzipped data, and the server in my example returns gzipped data. I only found out using wireshark.

Could it be that the gzipped data don't even reach the lua code?
