[nginx] svn commit: r5084 - trunk/src/http

[ru]

Author: ru
Date: 2013-02-27 13:22:20 +0000 (Wed, 27 Feb 2013)
New Revision: 5084
URL: http://trac.nginx.org/nginx/changeset/5084/nginx

Log:
Fixed separator in $sent_http_cache_control.

In case multiple "Cache-Control" headers are sent to a client,
multiple values in $sent_http_cache_control were incorrectly
split by a semicolon.  Now they are split by a comma.
