When I tried to use nginx and memcached module,  
the output always had a odd quotation mark  
before the cached content.

I have tried nginx/0.6.32 and nginx 0.5.34  
I used:  
ruby 1.8.7 (2008-06-20 patchlevel 22) [i686-linux] and  
ruby 1.8.7 (2008-06-20 patchlevel 22) [i686-darwin9]  
with  
memcached 1.2.5  
libmemcached 0.22  
memcached gem 0.11  
or  
memcached-client 1.5.0

here is my nginx conf file:  
worker\_processes 1;  
pid /www/logs/nginx.pid;  
events {  
worker\_connections 1024;  
}  
http {  
server {  
listen 80;  
server\_name localhost;  
location / {  
default\_type text/html;  
set $memcached\_key $uri;  
memcached\_pass localhost:11211;  
}  
}  
}

after I setup a cache:  
irb(main):002:0\> require ‘memcached’  
=\> true  
irb(main):003:0\> c = Memcached.new(‘localhost:11211’)  
#…  
irb(main):006:0\> c.set ‘/test’, ‘hello’

when I opened 127.0.0.1/test with safari 3.0 or  
Firefox 3, I didn’t get  
hello  
but:  
"hello

I get no idea where the Quotation mark coming from!!!  
Can anyone tell me how to fix it?

if you run memcached in verbose mode “memcached -vv” does it display  
the quote upon retrieving the key?

I started memcached with “memcached -vv”, I saw no cache content being  
shown:  
memcached -vv  
slab class 1: chunk size 88 perslab 11915  
…  
slab class 39: chunk size 489032 perslab 2  
\<6 server listening  
\<7 send buffer was 105472, now 268435456  
\<7 server listening (udp)  
\<8 new client connection  
\<8 get /test

> 8 END  
> \<8 connection closed.  
> \<8 new client connection  
> \<8 get /favicon.ico  
> 8 END  
> \<8 connection closed.  
> \<8 new client connection  
> \<8 set /test 0 0 9  
> 8 STORED  
> \<9 new client connection  
> \<9 get /test  
> 9 sending key /test  
> 9 END  
> \<9 connection closed.

But I noticed an interesting thing: ‘/favicon.ico’ was requested now and  
then. Do you think it may cause the problem?

I have just modified the nginx conf file and restarted nginx to filter  
all  
/favicon.ico request.worker\_processes 1;  
pid /www/logs/nginx.pid;  
events {  
worker\_connections 1024;  
}  
http {  
server {  
listen 80;  
server\_name localhost;  
#access\_log /www/logs/loc.access.log;  
location / {  
default\_type text/html;  
set $memcached\_key $uri;  
memcached\_pass localhost:11211;  
}

```
    location /favicon.ico {
       root /www/loc/public/images;
    }

}

```

}

But the quotation mark didn’t go away.
