I welcome, I have this problem because after logging on in joomla to the front side at once a problem with nginx appears is showing the error: 502 Bad Gateway. As long as won't log on that's all is acting correctly, and in logs something like that appear:
[code]
2011/02/15 13:34:47 [error] 9269#0: *36 upstream sent too big header while reading response header from upstream, client: xx.xx.xx.xx, server: mydomain.com, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "myhost.com", referrer: "http://mydomain.com"
[/code]
I configured nginx to the work around joomla according to what is here:
http://wiki.nginx.org/Joomla
And I installed nginx wedługo of guide on howtoforge.com which is approachable under this link:
http://www.howtoforge.com/installing-nginx-with-php5-and-php-fpm-and-mysql-support-on-ubuntu-10.10
I will add that on the second server I already have such a more previous problem I had in other datacenter. The problem with this mistake is disappearing how I will remove files cookie from my browser which concern my side. Perhaps does somebody know how to fix it?
Thank very much
