400 bad request request header or cookie too large nginx Rails app

  • Posted July 8, 2013


I am getting 400 bad request request header or cookie too large nginx with my Rails app, restarting browser fixes the issue. I am only storing a string id in my cookie so it should be tiny. Where can I find the nginx error logs? I looked at nano /opt/nginx/logs/error.log, but it doesn’t have anything related…

Any help

Thx Leo

Try increasing the large_client_header_buffers directive in nginx, <br> <br>server { <br>… <br>large_client_header_buffers 4 16k; <br>… <br>}

Yes, it dose. <br> <br>But it will come back again. I cannot find anything wrong with my code. So what is the best way to debug this? like I said I cannot find anything in /opt/nginx/logs/error.log <br> <br>thx <br>Leo

Try clearing your browser’s cookies, does that fix it?
