I am using nginx-full 1.6.2-5+precise0 from the PPA on Ubuntu 12.04

In one of the server configurations I have following section:

location ~ \d/$ {

if ($http_accept ~ (text|application)/x?html) {

add_header Content-Type "text/html; charset=utf-8";
rewrite (.*)/$ $1/index.html break;



I have noticed recently that requests to these URLs over HTTPS result in Chrome error ERR_SPDY_PROTOCOL_ERROR (even when I disable spdy). I will attach the log from chrome://net-internals/#spdy

I saw that removing add_header directive fixes this issue.

I only saw that in Chrome, Firefox was okay. Chrome version was 39.0.2171.95 (64-bit), I couldn't try other versions.

  • Resolution set to wontfix
  • Status changed from new to closed

Use of "add_header Content-Type ..." will result in a duplicate Content-Type header in a response. There is no surprise it causes problems in some cases. Note that the "add_header" directive is a low-level one and should be used with care - in particular, it's bad idea to try to use it to overwrite standard headers.

Instead, use the default_type and types directives to control MIME type of responses, and charset to set charset as needed.

I see. It would be nice to add this line to the documentation, because the breakage of a low-level protocol is not something you'd expect from adding a directive.
