I can confirm with the patch this compiles properly in a couple of
different Linux environments. Thanks Igor.

Feature: the ngx_http_degradation_module. ?

How does this work?

This module allow to return 204 or 444 code for some locations on low
memory condition:

http {
degradation sbrk=500m;

server {

   location /some {
       degrade  204;
   }

Currently it can be used if sbrk(0) syscall reports real memory volume
allocated by a proccess. It does not work for Linux and FreeBSD 7.0+
where
malloc() may use mmap(). It can be used on FreeBSD before 7.0 and on
7.0+
if MALLOC_OPTIONS=Dm.

Hi Igor,

Could you kindly explain these features in more details?

Thanks a lot,

server {

    root  $name;

location ~^(?<script_name>/.+\.php)(?<path_info>.*)$ {

proxy_pass  http://$backend;

Before you should add URI part:
proxy_pass http://$backend$request_uri;

msie_padding on; # default

The directive adds lines to the default error pages to increase their
size
to more than 512 bytes:
