NodeJS application behind APache2 reverse proxy get error "413 Request Entity Too Large" on upload files

Question

I work on a node.js application that permits its users to upload large files.

• When I run it on 8080 or 3000 or whatever, its okay.
• But when I access it on 80 behind apache2 with mod_proxy configured as reverse proxy, I get this error on upload (files > 1MB)

413 Request Entity Too Large

I tryed to add this directive to apache config :

LimitRequestBody 0

But it doesn't change this behavior. I don't know where to search the right conf.

Answer 1

Solved.

It seems Apache reverse Proxy works with mod_proxy but it also needs mod_proxy_http.

In my case all the application works fine with only the fisrt apart uploading files > 1MB.

I found references to mod_proxy_http and enabled it :

# a2enmod proxy_http
# apache2 restart

Now it seems work. I trying to upload larger and larger files to the server to test it. The last was 160MB and uploaded fine.
