Author: mdounin
Date: 2012-05-17 18:10:34 +0000 (Thu, 17 May 2012)
New Revision: 4642
URL: http://trac.nginx.org/nginx/changeset/4642/nginx

Log:
Fixed core variables dynamic access after reconfiguration.

If variable was indexed in previous configuration but not in current
one, the NGX_HTTP_VAR_INDEXED flag was left set and confused
ngx_http_get_variable().

Patch by Yichun Zhang (agentzh), slightly modified.
