unknown directive "if" nginx-0.7.60

[Alan Hysinger]

Hi,

Please forgive my newbness to nginx here.  I've tried a bunch of  
stuff, googling and searching the nginx mail forum, to no avail.

I am trying to setup nginx using memcached and I have an app running  
on an Apache backend.  I need all POSTs passed through to the backend,  
and GETs can be cached.  I've read the examples, made up a .conf file,  
and when I try to start nginx, I get this error:

----------------------------------------------------------------------------
[emerg]: unknown directive "if" in /home/mydomain/nginx/conf/ 
nginx.conf:26
----------------------------------------------------------------------------

If I comment out the if directive, then I get this error:

----------------------------------------------------------------------------
[emerg]: unknown directive "set" in /home/girlprops/nginx/conf/ 
nginx.conf:33
----------------------------------------------------------------------------

I want to add in here that with a different .conf, without trying to  
use memcached, and just proxy_pass to my backend, things were working,  
so I can demonstrate a little competency with nginx.  It's when I  
cobbled together .conf bits from various blogs about nginx+memcached  
that I started having problems.

Running under Fedora Core 10, built from source.  I figure I must not  
be compiling some module in or I have my location {} block in the  
wrong part of the .conf or some other n00b foolishness.  If someone  
can give me a pointer in the right direction, I'd appreciate it very  
much.  I'm pretty excited about being able to have a RAM resident  
cache running on my site, and also being able to create a substantial  
countermeasure against the latest DoS exploit by using nginx, not to  
mention, getting a few gobs of RAM back from using Apache as the front  
end.

Thank you for any help,
Alan
