HTTP Redis, SSI and error log

Server NGINX
1

Hello,

I am trying to use the http redis module for nginx basically like :

set $redis_key "$key";
redis_pass redisbackend;
default_type   text/html;
error_page 404 502 504 = @fallback;

But I have a curious message in error log !?

2011/01/21 17:45:38 [alert] 25902#0: *125149 unknown variable index: -1,
client: XXX.XXX.XXX.XXX, server: _, request: "GET /myUri/ HTTP/1.1",
subrequest: "/MySubrequest/", host: "Myhost"

How to remove it ?

Thanks in advance

set $redis_key “$key”;

What is the $key?

Examples for ngx_http_redis module available in README.

redis_pass redisbackend;

Provide more information about redisbackend description.

What is the $key?
set $redis_key “$http_host$document_uri$query_string”;

Provide more information about redisbackend
description.

upstream redisbackend {
server 127.0.0.1:6379;
keepalive 256 single;
}

Additional information : I’ve removed the line
static ngx_str_t ngx_http_redis_db = ngx_string(“redis_db”);

Because of error in compilation.
./configure … --add-module=…/ngx_http_redis-0.3.2
–add-module=…/ngx_http_upstream_keepalive-c6396fef9295
make && make install

Thanks you

Does it possible get “$http_host$document_uri$query_string” key-value
via redis_cli?
Could you please provide logs with this key?

keepalive options available only if you are compile nginx with
ngx_http_upstream_keepalive third-party module.

What is the platform do you using? You should remove -Wall from
your CFLAGS, as I told you in private letter.
Also, I fix compilation problem in future releases.

Yes, it can send the key. Even with your module. It works fine but there
are alert in errors logs.

Yes, no problem with that.
