nginx -> httpd -> mod_jk -> tomcat (no replies)

Hi everybody,

I recently begun using proxy with nginx (same tests were made with haproxy).

My needs are to proxy for failover and balancing tomcat: I need to serve lots of users with production app.


While I understood that a 100% tomcat AJP1.3 compatibility is achievable with apache httpd only and mod_jk, I successfully serve my app with apache to a simple 80 http port (cookie path already patched). So I decided to have a localhost apache httpd to proxy tomcat with AJP. IT works perfectly.

Now, I need to proxy httpd with nginx, adding SSL with letsencrypt. I successfuly configured the proxy and everything works but uploads: if I send a file to my app, only small uploads work.

I'd like to investigate the headers, maybe I need to transform some string but I'm a completely newbie from this point of view.

Do you have some tips on how to investigate the problem?


Thanks,




Giacomo Arru
