1241	Using uninitialized variable warning in SSI module	shmihas@…		"I have the following SSI code in my page:
{{{
<!--# if expr=""$_request_uri"" -->
    <!--# set var=""u"" value=""$_request_uri"" -->
<!--# else -->
    <!--# set var=""u"" value=""$uri"" -->
<!--# endif -->
}}}

If variable _request_uri is not set i always get warning in error log:
{{{
2017/04/07 12:35:25 [warn] 18#18: *76 using uninitialized ""_request_uri"" variable while sending response to client
}}}

If i use any other name for variable wich is not set no warning occures."	defect	closed	minor		nginx-module	1.11.x	invalid	ssi		Linux 4.4.20-1.el7.elrepo.x86_64 #1 SMP Wed Sep 7 11:44:03 EDT 2016 x86_64 x86_64 x86_64 GNU/Linux	"nginx version: nginx/1.11.8
