I’m trying to get nginx 1.3.8 to play well with the SPDY patch and  
mod\_zip. I don’t want to move to 1.3.9+ because I rely on the upload  
modules that have not yet been modified to handle the chunked uploads.

When initiating a download with mod\_zip, things appear to go ok until  
mod\_zip starts to feed the content of the subrequest into the output  
handler (spdy in this case). I get this in my debug log:

[debug] 5244#0: \*1 http init upstream, client timer: 0

It’s hardly possible to get help with this, given the fact that  
you are using non-latest nginx with non-latest experimental spdy  
patch and have problems with 3rd party module.

On the other hand, in any case it’s good idea to provide details  
as recommended on [GitHub - nginxinc/nginx-wiki: ARCHIVED -- Source for the now archived NGINX Wiki section of https://www.nginx.com · GitHub](http://wiki.nginx.org/Debugging), in particular  
full config to reproduce the problem, and a backtrace.
