I know that you can use nginx HttpGzipModule to gzip responses. Can you als use it to enable nginx to handle gzip-compressed requests, i.e. ones with the request header: Content-Encoding: gzip ?

Note: Apache, with the help of mod_deflate can handle gzip-compressed requests with the directive SetInputFilter DEFLATE.




I just tried this on an nginx server I have sitting in front of an Apache backend.

curl -H "Content-Encoding: gzip" --include -d @testfile.gz http://example.com/upload_file.php

curl automatically added:

Expect: 100-continue

to the request headers.

nginx sent back a

HTTP/1.1 100 Continue

response and curl followed up by sending the gzipped data. nginx passed the whole lot back to Apache, still compressed and still with the Content-Encoding: header intact.

If I didn't add the Content-Encoding: gzip header with curl, I didn't get the HTTP 100 response but everything else was the same.

This doesn't answer your question yet but it does imply that nginx either doesn't handle this by default or doesn't uncompress the body of the request when it is proxying. I'm interested in the answer to this one so I'll see if I can try it out on a non-proxying nginx server a bit later on.

Presumably you could solve the bandwidth problem by proxying those requests to an Apache backend with mod_deflate but that ignores the reason you chose nginx in the first place.

  • Thanks. Have you tried on a non-proxying nginx server? – ma11hew28 Apr 21 '12 at 22:27

Just found this article: Howto make Nginx decompress a gzipped request

It looks good, but I haven't tried it yet. Hope it helps.

    Whilst this may theoretically answer the question, please provide context around links so others will have some idea what it is and why it’s there. If possible summarise or quote the most relevant part of an important link, in case the target site is unreachable or goes permanently offline. – HBruijn Sep 15 '15 at 15:06
